The first weeks in the US decide a lot about the rest of the move. Almost all the problems below are well known and avoidable, and most have the same cause: deciding in a hurry and without information. Here are the 10 that come up most, and where to learn more about each.

1. Expensive housing or a rental scam

With no credit, renting is hard, and fake ads are common. Never pay before you see the property. See how to rent with no credit history.

2. Having no credit history

Your credit score affects renting, a car, a phone plan and even some jobs. Start early. Read how to build credit.

3. Depending on a car

In many areas there is not enough public transit, and a car is expensive. See what a car costs and how to choose where to live.

4. No Social Security number

Some services ask for an SSN, and not every immigrant can get one. Check how the SSN works.

5. Missing documents

Passport, I-94, proof of address and copies of everything. See which documents to get when you arrive.

6. Health care costs

A doctor visit or an emergency room trip without a plan can cost a lot. Read about health insurance and emergency care for immigrants.

7. Scams aimed at immigrants

Fake "notarios," promises of a fast green card, calls claiming to be from ICE. Learn how to protect yourself from reports, extortion and scams and what ICE is.

8. Working without authorization or without being paid

Working without authorization puts your status at risk, and you still have rights. See informal work: risks and rights.

9. Trouble with English

Banks, doctors, landlords and employers are dealt with by phone and in writing. Understand why English matters so much.

10. Isolation and culture shock

Being far from family and friends weighs more than you expect in the first weeks. Look for Brazilian communities, church, sports or language groups, and keep a simple routine. If tiredness or sadness lasts, seek professional support.

A simple plan for the first week

  1. Organize your documents and make copies, on paper and in the cloud.
  2. Decide where you will live, without paying in advance before you visit.
  3. Open a bank account and keep your proof of address.
  4. Work out how you will get around, with or without a car.
  5. Research a health plan and the nearest clinic.
  6. Choose carefully who you share personal information with.

If you want the complete step-by-step, with the mistakes every Brazilian makes, it is in the book.
