My friend and his wife have some differences. However, they were married in good faith and he obtained a Conditional Green Card. Can he now obtain his Green Card if their marriage ends in divorce?

Unfortunately, your friend has the onerous task of overcoming a presumption in the law that allows married citizens to obtain a Green Card [Alien Registration Card] in the first place. The presumption is that all marriages are ‘sham’ marriages, unless proved otherwise. The two-year conditional permanent residence is a probationary period and the marriage must last beyond this period for the individual to be entitled to Permanent Resident status in the United States [the card itself is valid for 10 years and is renewable]. It is imperative that the marriage lasts beyond the two-year period for your young friend to stay here permanently.
