i have green card i wanna get married with my girlfriend who has student visa F1 , how long take her to get her green card and can she travel over

For the month of January 2013, the F-2A category for spouses and children of permanent residents is available for petitions filed before September 22, 2010, worldwide except for those born in Mexico (which is backed up to 9/1/10). A guesstimate is that the time to become current will be between 2 – 3 years. During that time, the best advice for your wife would be to remain in the States. F-1 visa status is based upon nonimmigrant intent, and an indication that she is married to a permanent resident who has petitioned for her green card may cause problems with visa renewal or even reentry into the U. S. at a port of entry.
