Hello i was deported 14 yrs ago because i was arrestes at the san ysidro port of entry with 150 pound of marihuana . Convicted or possesion with intent to sell . After some years i was recruted as a confidential informant by the customs deparment and worked for them and got issued a múltiple entry for about 3 years . My question is if my life is in danger as a result of my envolment with them , can i get some kind of visa or will it help to get my permanet residence back?
