Quick Answer

Your first 90 days in the U.S. require tackling essential bureaucratic tasks in a specific order: Social Security Number (needed for everything else), bank account, credit card (start building credit immediately), phone plan, permanent housing, driver's license, and healthcare setup. Many tasks depend on others (can't get apartment without credit, can't build credit without SSN), so sequence matters. Budget $5,000-$10,000 for deposits, initial expenses, and setup costs beyond your first month's rent.

Key Takeaways

  • Social Security Number comes first: You need it for banking, credit, employment, and almost everything else.

  • Temporary housing initially: Book 2-4 weeks of Airbnb while you apartment hunt and get documents.

  • Credit building starts day one: Get secured credit card immediately. Every month without credit history is wasted.

  • Order matters: SSN → Bank → Credit Card → Phone → Apartment → Driver's License → Everything else.

  • Front-load costs: First 90 days are expensive. Budget for deposits, furniture, and duplicative costs.

  • Documents are currency: You'll need passport, visa, I-94, and offer letter for almost everything.

Week 1: Critical Administrative Tasks

Day 1-3: Get Temporary Housing

Why temporary first:

  • Can't sign apartment lease without credit/references

  • Need U.S. address for SSN application

  • Need time to explore neighborhoods

  • Avoid rushed, bad rental decisions

Options:

  • Airbnb (easiest, 2-4 weeks)

  • Extended stay hotel

  • Corporate housing (if employer provides)

  • Friend's couch (cheapest but not ideal)

Cost: $1,500-$4,000 for 2-4 weeks

Day 3-5: Apply for Social Security Number

Why this is priority #1:

Everything requires SSN:

  • Bank accounts

  • Credit cards

  • Employment payroll

  • Apartment applications

  • Utilities

  • Phone plans

How to apply:

  1. Wait 10 days after entry (SSN system needs to sync with immigration)

  2. Visit local Social Security Administration office

  3. Bring: Passport, I-94, visa, job offer letter

  4. Fill out SS-5 form

  5. Free application

Timeline:

  • Application: 30 minutes

  • Receive card: 2-3 weeks by mail

Critical: Apply immediately. This is your longest-lead-time item.

Day 5-7: Open Bank Account

What you need:

  • Passport (with visa)

  • I-94 (print from cbp.gov/i94)

  • U.S. address (even temporary)

  • Initial deposit ($25-$100)

  • Some banks: SSN (though some will open without if you're waiting)

Best banks for new immigrants:

  • Chase (branches everywhere, good for newcomers)

  • Bank of America (immigrant-friendly)

  • Citibank (global banking if you have account back home)

  • Capital One (online, good early credit products)

What to open:

  • Checking account (for direct deposit and bills)

  • Savings account (start emergency fund)

Avoid:

  • Banks requiring SSN immediately (wait for yours)

  • Banks with high fees

  • Banks without many branches/ATMs

Cost: Usually free with minimum balance

Day 7-10: Get Phone Number

Why you need it:

  • Apartment applications require U.S. phone

  • Banking and security

  • Job communication

  • Everything requires 2FA these days

Options:

Postpaid (best if you can):

  • Verizon, AT&T, T-Mobile

  • Requires SSN and credit check

  • $50-$80/month

  • May require deposit without credit history

Prepaid (if no SSN yet):

  • Same carriers, prepaid plans

  • No credit check

  • $40-$50/month

  • Can switch to postpaid later

MVNO (cheap option):

  • Mint Mobile, Visible, Cricket

  • Use major carrier networks

  • $25-$40/month

  • Good for first few months

Recommendation: Get prepaid immediately, switch to postpaid once you have SSN and want to build credit with phone payments.

Week 2-3: Financial Foundation

Get Secured Credit Card

Why this is critical:

U.S. credit system penalizes having no credit history. Starting immediately matters.

How secured cards work:

  • You deposit $200-$1,000

  • That becomes your credit limit

  • Use card and pay in full each month

  • After 6-12 months, graduate to unsecured card

  • Deposit refunded

Best secured cards for immigrants:

  • Discover it Secured (good rewards, graduates quickly)

  • Capital One Platinum Secured (low deposit option)

  • Bank of America Secured (if you bank there)

Strategy:

  • Apply as soon as you have SSN

  • Make small purchases ($20-$50/month)

  • Pay in full every month (never carry balance)

  • After 6 months, you'll have credit score

This is not optional: Without U.S. credit history, you'll face:

  • Higher apartment deposits

  • Difficulty getting car loans

  • Higher insurance rates

  • Can't get mortgage later

Set Up Direct Deposit

With employer:

  • Provide bank account routing and account number

  • First paycheck may still be paper check (bank can deposit)

  • Verify deposit timing (weekly, biweekly, monthly)

Understand Your Paycheck

Deductions you'll see:

  • Federal income tax (20-30% typically)

  • State income tax (0-13% depending on state)

  • Social Security (6.2%)

  • Medicare (1.45%)

  • Health insurance premium

  • 401(k) contribution (if you enrolled)

Your take-home: Roughly 65-75% of gross salary

Shock factor: If offered $100K, expect $5,400-6,200 per month take-home.

Week 3-4: Housing and Transportation

Apartment Hunting

What landlords want:

  • Proof of income (3x rent in gross income)

  • Credit report (you won't have yet)

  • Background check

  • References

  • First month + last month + security deposit

How to overcome no credit:

  • Offer 2-3 months rent upfront

  • Get letter from employer verifying income

  • Offer larger security deposit

  • Use international credit report (if available)

  • Consider corporate housing/sublease for first 6 months

Where to search:

  • Apartments.com, Zillow, Trulia

  • Craigslist (careful of scams)

  • Facebook housing groups

  • Walk around desired neighborhoods

Cost: Expect to pay 3x first month's rent upfront

  • Example: $2,000/month apartment = $6,000 upfront

Furniture and Setup

Budget options:

  • IKEA (affordable, easy to assemble)

  • Facebook Marketplace (used furniture cheap)

  • Amazon (everything delivered)

  • Thrift stores (Goodwill, Salvation Army)

Essentials first 30 days:

  • Bed and mattress ($300-$1,000)

  • Kitchen basics ($200-$400)

  • Cleaning supplies ($50-$100)

  • Bathroom items ($100-$200)

Skip initially:

  • Living room furniture (use floor cushions temporarily)

  • Decorative items

Total furniture budget: $1,500-$3,000 for basics

Transportation

First 30 days:

  • Uber/Lyft (expensive but flexible)

  • Public transit (learn the system)

  • Walking/biking (explore neighborhood)

Month 2-3 decisions:

Buy a car if:

  • Living in car-dependent area (most of U.S.)

  • Public transit inadequate

  • Can afford $300-$500/month (payment, insurance, gas)

Skip car if:

  • Living in NYC, SF, DC, Chicago, Boston (good transit)

  • Work from home

  • Everything walkable

Getting driver's license:

  • Requirements vary by state

  • Usually: Written test + driving test

  • Some states require SSN, some don't

  • Some states accept foreign licenses, some don't

  • Cost: $30-$100

  • Timeline: 2-6 weeks depending on state

Week 4-8: Healthcare and Additional Setup

Health Insurance

Through employer:

  • Enroll within 30 days of start date

  • Choose plan based on expected usage

  • Understand: Premium, deductible, copay, out-of-pocket max

If employer doesn't offer:

  • Healthcare.gov (marketplace)

  • Private insurance

  • Very expensive without employer subsidy

Find doctors:

  • Primary care physician (annual checkup)

  • Dentist (dental separate from health insurance)

  • Specialists as needed

Utilities and Services

Set up:

  • Electricity/gas (usually bundled)

Cost expectations:

  • Internet: $50-$100/month

Connect with Community

Find your people:

  • Meetup.com (professional and social groups)

  • Facebook groups for your nationality in your city

  • Alumni networks (university alumni groups)

  • Religious/cultural organizations

  • Work colleagues

Why this matters:

  • Loneliness is real challenge

  • Practical advice from those who've done it

  • Job opportunities come from networks

  • Emotional support during adjustment

Week 8-12: Optimization and Long-Term Setup

Optimize Banking

Once you have credit score (6+ months):

  • Apply for rewards credit card (2-5% cash back)

  • Open high-yield savings account (4-5% APY)

  • Consider investment account

File W-4 Correctly

Review tax withholding:

  • Too much withheld: You're giving government interest-free loan

  • Too little: You'll owe at tax time

  • Adjust based on your situation

Set Up Retirement

401(k) through employer:

  • Contribute at least enough to get employer match

  • Employer match is free money

  • Tax-advantaged savings

IRA (Individual):

  • Additional retirement savings

  • Roth IRA if eligible

  • $7,000/year limit (2025)

Understand Your Benefits

Review everything:

  • Health insurance details

  • Life insurance (if offered)

  • Disability insurance

  • FSA/HSA (health savings)

  • Stock options (if tech company)

  • Paid time off policy

Common First 90 Days Mistakes

Mistake 1: Not applying for SSN immediately

Every day of delay pushes back everything else.

Solution: Apply within first week after 10-day wait period.

Mistake 2: Signing long apartment lease too quickly

You don't know neighborhoods yet. Rushed decisions lead to regrets.

Solution: Temporary housing first. Take 3-4 weeks to explore and decide.

Mistake 3: Not starting credit building

Waiting even 6 months means 6 months less credit history.

Solution: Secured credit card as soon as you have SSN.

Mistake 4: Overspending on furniture

Tempting to furnish entire apartment immediately.

Solution: Buy essentials only. Add gradually over 6-12 months.

Mistake 5: Not budgeting for double costs

First 90 days have overlapping expenses (temporary + permanent housing, etc.).

Solution: Expect to spend 2-3x normal monthly expenses in first 90 days.

Frequently Asked Questions

1. How much money should I bring for first 90 days?

$10,000-$20,000 depending on city and lifestyle. More for NYC/SF, less for smaller cities.

3. When will I get my first paycheck?

Usually 2-4 weeks after start date, depending on company pay schedule.

4. Should I buy furniture or rent it?

Buy basics. Renting furniture is expensive over time.

5. Do I need a car immediately?

Depends on city. NYC/SF/DC: probably not. Houston/Phoenix/most suburbs: yes.

6. How do I know which health insurance plan to choose?

If healthy and young: high deductible, low premium. If you have ongoing care needs: low deductible, higher premium.

7. Can I use international credit score?

No. U.S. has separate credit system. You start from zero.

700+ is good, 750+ is excellent. You'll start around 650-700 after 6 months of secured card.
