text: my friend wants to get married to a  man, , he is an illegal alien, she is not. how does he become a citizen? she is a citizen of the us, but they arent sure who to contact for him to become one as he is an illegal alien, he needs more supporting papers. they can get marry and he would become a citizen.  it is a long process,, not all who married a citizen becomes one because some may have a record and that would be the problem of deportation...even  if he is an illegal and no worries of bad record on the country of origin, there is no problem..
