My mum has been in USA since Dec 2000 for work, in 2003 She return to Europe and retired. She than decided to come back and live near me. in the mean time I became citizen (2009) and start sponsoring her in 2010, to finalize the paper she was ask to go back to her country and was told that she couldn't come back because she overstayed her visa. Does the ban applied since 2003 or 2010??She enter the US LEGALLY with a regular tourist visa. I guess she cannot come back in the US as of right now!? What can/should I or she do(es)?
