it is unclear what was his immigration status when he was deported. If he has a green card, he lost it anyway. If he wants to return to the US, he must apply for visa. if he has immediate USC relatives, they can file petition for him. However, his criminal conviction may render him inadmissible. He should consult with an immigration lawyer to determine his chances and options.
