A family touches down at a US airport with two suitcases of emotion: relief that the visa journey is over, and overwhelm because everything ahead is new. In that state, the first week easily drifts by inertia — unpacking, grocery shopping, getting to know the neighborhood — while a chain of administrative tasks awaits: do them early and everything flows smoothly; do them late and your entire quarter of settlement gets pulled back by domino effect: no SSN means difficulty opening many things, no bank account means difficulty renting a home, no stable address means important mail gets lost.
This article structures the first week into an ordered checklist — because order is what newcomers don't know: which task must come before which, which is just for the principal applicant, which the whole family should do in one trip to keep things efficient. With this checklist in hand, your first week can still have afternoons exploring the new neighborhood — but with a clear head.
Day 0 — At the Airport and First Night: I-94 for Each Person
The first administrative task of the entire journey: within the first 24-48 hours, access the CBP's online I-94 system, retrieve and download the I-94 record for each family member — verify three things: correct category (L-1A for principal, L-2 for family), correct expiration date (matching the authorized period), correct name spelling per passport. I-94 is the document that defines your legal status in the US — more important than the visa stamp in your passport — and errors here (wrong category, wrong date) are simple to fix if caught early, but become major issues if discovered late, exactly as the status maintenance article warned.
Same first night: photograph and back up to the cloud all original documents for the entire family (every passport page with stamps, visas, the I-94 you just downloaded, vital records you brought) into a family folder structure — your personal version of the digital archive that businesses maintain, and which you'll pull from for every procedure ahead.
Days 1-2 — Phone SIM and Mailing Address: Two Lifelines
A US phone number is a required field on nearly every form you'll fill — so it tops day one's schedule: get a prepaid SIM at a carrier store with your passport (switch to a postpaid plan once you have SSN and history), one number per adult. Same day: lock in a stable mailing address — temporary rental, a friend's place, or a mailbox service — because the most critical documents of this phase (SSN card, bank cards, vehicle papers) all arrive by mail, and changing addresses mid-stream is a formula for lost mail.
Tip from those who went before: if your long-term housing isn't settled yet, use one single stable address for all registrations in the first month, then update once when you move — rather than a different address for each form based on where you're actually staying each week. Separately, mark the USCIS address change obligation when you move (required form, has a deadline) straight into your family calendar now.
Days 2-4 — SSN for Principal Applicant: The Number That Unlocks Everything
L-1 holders are eligible to apply for a Social Security Number — and should apply in the first week because nearly everything financial depends on it (the credit score article already mapped out the dependency chain). Process: go to your local SSA office (find address and hours on the official website; some locations require appointments) with passport, visa, and I-94 copy. Technical note: SSA's system needs entry data to be synced — arriving too early (1-2 days after landing) sometimes gets you asked to return, so days 3-5 are usually the sweet spot; the card arrives by mail in a few weeks but the number can be issued sooner.
Spouse on L-2: the SSN path is tied to work authorization — handled on a later schedule (separate article on L-2 in this section); children don't need SSN for school enrollment. While waiting for the SSN card: don't let the task chain stall — banks and landlords both have workarounds that don't require SSN, as the next articles show.
Days 3-5 — Personal Bank Account and Foundation Accounts
Open a checking + savings account pair for both spouses using passport + visa + address document (most major banks accept customers without SSN, you add the number later) — this is the family wallet in the two-wallet discipline that has become law for the entire journey, and where you'll receive living expense transfers from Vietnam through personal channels. Same round: activate debit cards, install the bank app, and if the bank has a secured card program for newcomers — ask about it to plant credit history seeds from week one.
Other foundation accounts from this round: utility accounts for your rental (electricity-water-internet usually needed when signing lease; some places require deposits from those without history), and online profiles with systems you'll use regularly (I-94 portal, SSA website, tax portal when tax season arrives). Each account gets one line in your family's shared management file — a small habit that saves hours of lookup later.
Days 5-7 — Fitting Into the First Quarter Picture and Three First-Week Mistakes to Avoid
By end of week one, your checklist should show: I-94 for everyone checked and saved, SIM + stable address secured, SSN application submitted, bank account running, digital document archive complete. From that foundation, the major tracks of your settlement quarter open up per the section's dedicated articles: long-term housing, school enrollment for children, health insurance, driver's license and vehicle — and for the principal: week two begins shifting focus to the business side per the timeline the section's operations guide has mapped.
Three first-week mistakes made by many families before you: signing long-term contracts in a rush (expensive phone plans, rentals not thoroughly reviewed — everything week one should be in flexible version), spending large cash without keeping receipts (the document discipline of the journey applies from day 0, including major family expenses), and forgetting your own rest rhythm — jet lag plus overload is the formula for wrong signatures; a good first week is one where you finish this checklist, not one where you finish everything.

Frequently Asked Questions
What must I do first immediately upon arriving in the US?
Check the I-94 online for each family member within the first 24-48 hours: correct category (L-1A/L-2), correct expiration date, correct name per passport — I-94 defines your legal status and errors caught early are simple to fix, but late discovery becomes a major issue. Next in order: phone SIM, stable mailing address, submit SSN application, open personal bank account.
What documents do I need for SSN and how long does it take?
Principal L-1 applicant brings passport, visa, and I-94 copy to your local SSA office (some locations require appointments). The sweet spot is days 3-5 after entry so data has time to sync — arriving too early sometimes results in being asked to return. The card arrives by mail in a few weeks; while waiting, banks and landlords both have paths that don't require SSN so your task chain doesn't stall.
Can I open a bank account without an SSN?
Yes, at most major banks: passport + visa + address document is enough to open checking/savings accounts; add SSN later when you have it. Open immediately in week one since this is the family wallet receiving living expense transfers from Vietnam through personal channels — and ask about secured card programs for newcomers to start building credit history early.
Should a newly arrived family stay temporarily or sign a long-term lease right away?
Week one should be in flexible mode (short-term rental, extended-stay hotel) and use one single stable mailing address for all registrations — signing a long-term lease in a rush and jet lag is one of three classic first-week mistakes. Long-term housing has its own process and documentation worth doing carefully in weeks 2-3, per the housing article in this section.
