May I ask you another question? Do American green card holders have to stay in the United States 180 days a year? This 180 day is 65438+ 10 month every year.

Green card: it is a certificate issued by the United States to foreigners that they can live permanently in the United States. When you leave and go through the U.S. customs, U.S. customs officials will ask how long you have lived outside the United States; If you expect to leave the United States for more than one year, you can apply for re-entry permit (white paper). When you return to the United States, customs and immigration will not have any problems; If you haven't applied for the white paper, but it's more than one year, the customs will question whether you need permanent residence. If it often exceeds six months (meaning that you have lived in the United States for less than 180 days), the Customs and Immigration Department will detain your green card until you have reasonable reasons and proof. As for zero, when applying for American citizenship, there is such a requirement: from the date of application, you must live in the United States for no less than 933 days in the past five years and leave the United States for no more than 65,438+080 days every year to meet the requirements of applying for American citizenship. If it exceeds 180 days, it means that you will recalculate the next five years from the day you return to the United States again. If you apply for the white paper, although it has been more than a year, you can still calculate that you can apply for citizenship as long as you have lived in the United States for more than 933 days in the previous five years. Therefore, to sum up, there is no saying that the holder of a green card is required to live in the United States for 180 days. Only by applying for citizenship will you have time to stay in the United States. My friend 1995 got a green card and has been running between the two countries. /kloc-0 left the United States for more than seven months in 1999, and/kloc-0 didn't live in the United States for the longest four years from 1999 to 2005. He planned to be naturalized in early 2005, and then lived in the United States from 2005 to 20 10 for a total of 938 days, no more than 6 months at a time. As for Canada, Mexico and other countries, as long as you go to these countries and there is no entry stamp on your passport, you don't have to be outside the United States, because when filling out the application, you need to calculate the time when you leave the United States according to the entry and exit records of your passport.
