How to maintain the green card

Preservation of evidence: evidence with its own name, such as water, electricity, gas, telephone bills, lease or title deeds, payment of housing loans, or local taxes in the United States, should be preserved. All evidence addresses should be the same. Hold a valid re-entry permit: when applying for a re-entry permit, the person must be in the United States and must go to the immigration office for fingerprint printing about two months after the application is sent. Income tax declaration: Unless permanent residents have retired, they have to file tax returns every year. If a permanent resident has income but fails to file tax returns, the immigration law will consider him to have given up his right of abode. Declare income to meet the needs of life and travel. If you only declare the income from working abroad, it is inevitable to work and live abroad unless you apply for N-470. Apply for N-470: Have lived in the United States for more than one year after getting a green card; People who have been sent by the U.S. government or company to work overseas for more than one year and then return to the United States can apply for N-470. N-470 can retain the naturalization qualification and has the effect of retaining the green card. This application must be made within one year of assignment. Observe the time limit for leaving the United States: each time you leave the United States, it shall not exceed 180 days; Otherwise, when you return to the United States, the Immigration Department can ask you whether you have given up your permanent residency. Don't give up your green card: when you enter the airport, even if you are questioned by the immigration officer, as long as you don't sign to give up your green card, the immigration office must let you enter the country and wait for the immigration court to further examine whether to confiscate your green card. When you appear in court, you can use the above evidence to keep your green card. Signing a waiver may allow you to enter the country as a B-2 tourist, but you don't have a green card. Next time you come to America, you must sign a B- 1/B-2 or other non-immigrant visa. Seek a lawyer after entering the country: Although the airport immigration officer has no right to confiscate the green card, he can only temporarily detain it until the immigration court decides, but he can accept your giving up the green card, so he will generally put pressure on you to sign it. If you want to keep your green card, don't give in to this pressure and talk to a lawyer after entering the country. The first three items listed in this article must be done well in peacetime, otherwise even if there are lawyers and no evidence, it will be difficult to win the lawsuit in the immigration court.
