Will the green card of American soldiers be invalid? It has been 20 years since American soldiers retired from the army and returned to China. Will permanent residency expire?

There is no specific condition for the green card to expire in the United States, but the general condition is that your green card will expire after you lose your immigration tendency.

The green card is conditional and valid. It hasn't been updated for 20 years. It must be an expired green card. You have to go through the formalities again. The green card you are getting now is not recognized by the border guards in China, nor by American ports.

But the fact that you served in the United States army still exists.

Your terms are acceptable: 1. Apply for renewal of your green card. 2. Apply for a new green card.

But the complexity of your case may be beyond your own scope. You might think, 1. Contact the American Veterans Aid Organization, hoping that they can give you legal aid, give you advice and help you solve it. 2. Consult an American immigration lawyer.

In the 1990s, the United States rarely recruited foreigners into the army. Later, in the war between Afghanistan and Iran, foreigners were recruited because of insufficient troops.

You will be naturalized soon, so you won't be abolished, but you haven't.
