A clear, hour-by-day plan for your first week in America — from your SIM card and bank account to the documents you must not lose.

The first week in a new country is a blur of jet lag, paperwork, and a hundred small decisions. The goal of these seven days is not to finish everything — it is to build the tiny foundation (a phone number, an address, a bank account) that everything else plugs into.
In a nutshell
In week one, prioritize the things that unlock other things: a US phone number, a US address, and a bank account. Keep your passport, I-94, and visa documents safe, get a local SIM the day you land, and don't rush into credit cards or big purchases yet. Everything else can wait until you're rested.
Day 1: Phone, cash, and rest
Get a US SIM or eSIM before you leave the airport, or on day one. A working US number is required for almost every signup — banks, apartments, rideshare. Prepaid carriers like Mint, US Mobile, or T-Mobile prepaid need no credit check. Keep a little cash for the first 48 hours, and then sleep. Decisions made on no sleep are expensive.
Day 2–3: Address and bank account
Most things require a US address. If you don't have permanent housing yet, a friend's address or your temporary stay works to start. With an address, passport, and visa you can open a checking account. Newcomer-friendly banks (Chase, Bank of America) and online banks accept you without an SSN — see our guide to the best US bank accounts for NRIs.
Day 4: Lock down your documents
Make digital and physical copies of everything: passport, visa stamp, I-94 (download from the CBP website), I-20 or DS-2019 if you're a student, offer letter, and vaccination records. Store one set in the cloud and keep originals in a single safe folder. Read our full list of documents to keep safe.
Day 5: Plan your SSN
If you're work-authorized, the Social Security Number is your key to credit, payroll, and more. You generally apply at a local SSA office after you arrive (students may need to wait until on-campus employment is set up). See what to do once it arrives in SSN: your financial next steps.
Day 6: Groceries, transit, and a phone plan
Set up the boring essentials: a grocery store routine, public transit card or rideshare app, and a permanent phone plan once you've tested coverage. Sort out utilities if you've moved into a place — our phone plan and utilities guide covers the setup.
Day 7: Breathe and make a 30-day plan
You don't need a credit card, a car, or an apartment lease in week one. Resist pressure to rush. Spend day seven mapping the next month — that's what our first 30 days guide is for.
Key takeaways
- Get a US SIM and number on day one — it unlocks every other signup
- Open a bank account with passport + visa + address (no SSN needed)
- Back up every document digitally and keep originals together
- Apply for your SSN as soon as you're eligible
- Don't rush credit cards, cars, or leases in the first week
Common mistakes in week one
- Carrying too much cash. Move money into a bank account quickly; don't keep thousands in a suitcase.
- Losing the I-94. Download it immediately — you'll need it for the SSN and leases.
- Signing a long lease while jet-lagged. Start with temporary housing if you can.
- Skipping the SIM and relying on hotel Wi-Fi — you'll get locked out of OTP-based signups.
Frequently asked questions
Can I open a bank account without an SSN?
Yes. Many US banks open checking accounts with just your passport, visa, and a US address. An SSN can be added later. See our bank account guide.
Do I need a US phone number right away?
Effectively yes — banks, apartments, and most apps send verification codes to a US number, so it's the first thing to set up.
When should I apply for a credit card?
Usually after your SSN arrives. Start with a secured card and build from there; there's no rush in week one.
The bottom line
Week one is about foundations, not finishing. Phone, address, bank account, safe documents — get those four right and the rest of your American setup has something to build on.
