a quick consultation with a lawer which usually does not cost more than $200 can make things crystall. Easy dude is right, i have seen lots of pending green cards for marriages with Americans.. however, recently a friend of mine got a green card within 4 months( conditional) of marriage. It was a real case. they were in love and living together for 3 years already. I think, if the marriage is with your age group and it does't look suspecious like , marrying 50 yr -0ld while you're 25, it happens fast.
