hi my name is Marian.me and my girlfriend Veronika are from Slovakia.i'm US citizen now and we are going to get married in three weeks.we got 2 months old daughter born in US.after our marriage we are going to apply for green card for Veronika.them wait to get it but our plan for next year is to leave US probably in may 2011 for couple of months.could be 6-12 or more months(maybe stay there for few years) because we both have families there so we would like to raise our kid there(Slovakia).what would happened to Veronika's green card if we decide to stay there for more then 6 months.or is there any legal way to extend our stay there without her loosing the card?
