As many as 9 million green cards could be handed out in the early going.

Obama can't issue green cards.

[LeoMcNeil]

Correct me if I’m wrong but green cards are issued by the Federal government by an agency managed by the President. Congress doesn’t handle administrative matters such as green cards, neither does the Supreme Court. That leaves the executive branch, headed by Obama. So yes, the President can issue green cards. Legally is another issue.
