Permanent residents of the United States eighteen years of age or older must carry their actual green card at all times. Failing to do so is a violation of the Immigration and Nationality Act, carrying the possibility of a fine up to $100 and/or imprisonment for up to 30 days for each offense.[4] Only the federal government can impose these penalties.[5]
Green cards are valid for 10 years for permanent residents, and 2 years for conditional permanent residents. After this period, the card must be renewed or replaced.[/b][/u]
Her claiming she didn't know is a load of Bull Excrement! As a permanent resident she has had to renew her green card at least once, or has she been in violation of that too?
