How can I maintain my green card status if I can't live in the United States for a long time?

According to US immigration law, if a green card holder stays outside the United States for more than 180 days, even if he doesn't voluntarily give up his green card, the US Immigration Bureau has the right to question whether he still has the intention to regard the United States as a long-term residence when applying for re-entry with a green card. But this does not mean that if the green card holder returns to the United States for a few days every six months, he will not lose his permanent residency. If you keep going back to the United States every six months, there may be no consequences in the first two to three years, but after a long time, the risk of being considered by the immigration authorities to give up your intention to stay in the United States permanently increases.

The correct way is for the green card holder to inform the US Immigration Bureau in advance that he may leave the United States for more than half a year. By applying for a re-entry permit, he shows that he has no intention of giving up his permanent residency. If you can't avoid living outside the United States for a long time, then keep the following evidence to answer the immigration question about your permanent residence intention:

1. Pay the income tax according to the regulations of the IRS every year, and keep the tax return records.

2. Have a residential address in the United States.

3. Have a bank account in America.

4. Hold a valid American driver's license and carry it with you when you enter the country.

I have an American credit card.

6. Owning houses, automobiles and other industries in the United States.

7. Bring your social security card.

8. Keep the green card within the validity period and apply for a new green card before the expiration of the validity period.
