B1 B2 Visa Family Appointment for Family Medical Travel

Your dad's bypass is on the 14th. Your brother can get the time off work. Your aunt wants to come and help your mom. And somewhere in all of that, somebody has to work out how four adults and one toddler get visitor visas in time — and whether that's one appointment or five.

That last part is the question nobody answers. There's plenty out there on what a B1/B2 visa is. Almost nothing on what you actually do when more than one relative is applying at once, on a clock, for a medical reason. So here's the whole thing end to end, in the order you'll hit it.

Does a family medical trip fall under B1/B2? Matching the trip purpose to the right visa

Two different visas live under that one label, and it helps to know which one you're asking for.

B-1 is for temporary business travel. B-2 is for tourism and leisure — and that's the wider one. It covers visiting family, taking a vacation, and receiving medical treatment in the U.S.

That means almost everyone on a family medical trip is a B-2 case:

• The relative traveling to be with the patient — visiting a family member is squarely B-2 territory.
• The patient themselves, if they're coming to the U.S. for care — receiving medical treatment is also B-2.

Nobody in this group is on B-1 unless they're genuinely doing business work while they're there. In practice, most people get a visa stamped B1/B2, which covers both. Don't let that confuse you at the interview. The officer still wants to hear the real reason for the trip, and "my mother is having surgery and I'm coming to be with her" is a B-2 reason.

One more thing worth checking before you do anything else: if your family members hold passports from certain countries, they may be able to visit the U.S. for up to 90 days without a B-1/B-2 visa at all. That changes the whole plan — no appointment, no interview, no waiting. Check that first, because it might save you weeks.

Booking appointments for multiple family members: group slot vs. one appointment each

Here's the part everyone's forum post is actually about.

There is no family visa. Each person is a separate applicant, with a separate passport, a separate application form, a separate interview, and a separate visa. That part is not negotiable.

What's flexible is scheduling. Some consulates will let a family group be booked together or into back-to-back slots. Others only let you book one applicant at a time. It varies by post, which is why that person applying for five family members never got a clean answer online — there isn't one universal answer.

What you can control:

• Finish every application form first. You need each person's confirmation number before you can book anything. Trying to book while still filling out forms for three other people is how appointments get lost.
• Add everyone to the same account or profile if the online appointment system lets you. Where it does, you'll often see a way to schedule a family together.
• If it only lets you book one at a time, book one at a time — but stack them. Same day, consecutive time slots. That keeps the family trip to one visit, one set of travel plans, one hotel night.
• Ask the call center. Each country has a U.S. call center number listed for appointment help. If the website won't tell you whether your consulate groups families, that's exactly what the phone line is for.
• Check the consulate's own page for interview waivers. Some posts let certain applicants skip the in-person interview entirely. If a grandparent or a young child qualifies, that shrinks the group you're scheduling.

Appointments can be booked online through the U.S. visa appointment system, or by phone. Do the booking from one computer, with one person in charge of it, and have every passport and confirmation number open in front of you.

The medical letter: what it's for and why expedited visa requests depend on it

A medical letter is the document that turns "my dad is sick" into something a consulate can act on.

It's a letter from the treating side — the doctor or the hospital in the U.S. — that explains, in plain terms, what's going on and why the relative's presence matters. It's not a permission slip and it doesn't guarantee anything. It's the evidence that supports an expedited appointment request, and without it you're just asking for speed with nothing behind the ask.

Ask the hospital's international patient office if there is one. Big treatment centers deal with this constantly and can usually produce a letter quickly.

What it should contain:

• The patient's full name and date of birth
• The condition or diagnosis, in plain language
• The treatment planned or already underway
• Dates — surgery date, admission date, treatment window
• The hospital name and city
• Why the family member's presence is needed
• The doctor's name, title, signature, and a contact number
• Hospital letterhead, and a date on the letter itself

Get it in writing, get it early, and get a copy for every applicant. This one document is the hinge the rest of the process swings on.

Requesting an emergency or expedited appointment around treatment dates

Rough order of operations:

1. Get the treatment dates first. Not "sometime in spring." A date.
2. Complete every application form and pay the associated steps the system asks for.
3. Book the soonest regular appointment you can find at the consulate that handles your area.
4. Then request expedited processing through the appointment system, explaining the medical situation and referencing the medical letter.
5. Follow up by phone to the listed call center if the online system doesn't offer an expedited option or you don't hear back.
6. Don't buy plane tickets until the visas are in hand. Treatment dates move. Visa decisions take as long as they take, and only the consulate can tell you anything real about that.

Two honest cautions. First, an expedited request is a request. The consulate decides, and not every request gets granted. Second, if the regular appointment you found is already early enough to beat the treatment date, you may not need to request anything — save the request for when you actually need it.

Documents family members should bring to the B1/B2 interview

Every applicant should carry their own set, in their own folder. Originals where you have them, photocopies as backup.

• Passport, valid well beyond the planned trip
• The application confirmation page (DS-160 barcode page)
• Appointment confirmation
• Photo, if the process asks for a printed one
• The medical letter
• Treatment documentation — admission letter, surgery schedule, hospital correspondence
• Proof of relationship to the patient — birth certificate, marriage certificate, family records
• Proof of ties at home — job letter, business ownership, property, school enrollment for kids
• Bank or financial documents showing the trip can be paid for
• Return plans — a rough itinerary, not a booked ticket

The officer decides what matters in the moment. Your job is to have it all and hand it over when asked. Answer questions directly, and don't volunteer long explanations.

The 90-day question: Visa Waiver Program visitors vs. B1/B2 holders

The 90-day number comes up a lot, and it's usually being applied to the wrong group.

For Visa Waiver Program visitors — people from certain countries — 90 days is the outside limit of a visa-free visit. That's where the number lives.

For someone holding an actual B1/B2 visa, the 90 days does not work the same way. How long a B1/B2 holder may stay is set when they arrive, and it's written down for them at that point. It is not automatically 90 days. Don't build your family's plan around a number you read on a forum. Confirm the current rule with the consulate before you rely on it.

How long can family stay, and when an extension becomes a bad idea

For a B1/B2 holder, the length of stay is decided at the port of entry and recorded for the traveler. That record — not the visa, and not the length of the visa — is what governs how long they can be there.

If the trip genuinely needs to run longer, there is a formal extension process, and it has to be filed before the allowed stay runs out. That's the mechanics.

Now the warning that official pages tend to bury. Extending a B1/B2 so a relative can stay on as a caregiver is a very bad idea. Multiple sources say it plainly, and they're right to. A visitor visa is for visiting. Caregiving that starts to look like work — a routine, a shift, a job — puts the visa and any future entry at risk. Don't plan a six-month stay around being the family's nurse.

If the patient is going to need ongoing care, that's a conversation to have with the hospital's social worker or care coordinator, not with a visa officer. Those are the people who can actually arrange home health, rehab, or a care facility. Solve the care problem where care is delivered.

Timing the application around surgery, treatment, or a hospital admission

Work backwards from the medical date, not forwards from today.

If the treatment is scheduled months out: you have room. Book normal appointments, gather documents without rushing, and skip the expedited request.

If it's a few weeks out: book immediately, request expedited the same week, and have the medical letter ready before you file the request. Every day you wait makes the window tighter.

If it's sudden — an ICU admission, an emergency surgery: you're in expedited territory from the start. Get the letter the same day if you can. Call the appointment line rather than relying only on the website.

One more piece of sequencing that families forget: you don't all have to arrive at once. Treatment can run for weeks. If three relatives are coming, staggering the arrivals spreads out the cost, keeps somebody home to handle things, and means someone's still there in week three when the first person has to fly back. Book the appointments together. Book the travel separately.

Traveling with a baby or toddler: what changes at the interview and on arrival

The toddler is not an accessory. They're an applicant.

That means their own passport, their own application form, their own appointment, and their own visa. A child can't ride on a parent's passport for this. Add them to the family booking like any other relative.

At the interview, bring the birth certificate. You may be asked to show the relationship, and if only one parent is traveling, be ready with documentation showing the other parent knows about the trip.

On the day of travel, everything in one folder: the child's passport and visa, the birth certificate, and the medical letter. That letter does double duty — it explains why the family is traveling and it's useful if anyone questions the purpose of the trip at the airport.

Practical bits that make the flight survivable: gate-check the stroller, bring the car seat if you'll be in cars on the other end, pack more formula and snacks than you think you need, and feed during takeoff and landing to help with ear pressure. If the child is the patient rather than a companion, the medical letter should cover the child's treatment, not a relative's.

Three quick answers before you log in to the appointment system

What is the 90-day rule for a B1/B2 visa?

In the research behind this guide, the 90-day figure shows up as a Visa Waiver Program limit — family from certain countries can visit for up to 90 days without a B-1/B-2 visa. How the 90-day rule applies to someone holding an actual B1/B2 isn't spelled out anywhere reliable. Ask the consulate.

What documents do parents need at the B1/B2 interview?

There's no single published checklist for a parent's interview. The one document that turns up consistently is the medical letter, used to support an expedited request. Everything else sits in the list above. The appointment itself gets booked through the U.S. visa online appointment system.

Can you get an emergency visa to visit a sick relative?

The route is an expedited request backed by a medical letter. Whether family members need a B1/B2 at all can depend on their country of origin. Nothing about this guarantees an emergency appointment will be granted — treat the medical letter as the way you make the request, not a promise of the answer.

Your consulate or embassy is the only place that can tell you how expedited appointments work at that specific post, and what they want to see in the request. Call them, or follow the instructions on their own page. And before you book a single slot, get the treatment dates confirmed by the hospital in writing — because every other decision you make here depends on that one date.
