Thanks .
Do you know - when does the one year starts ?
The date the visa was approved. In that case he has until April 10 to come back
The date the of Port of entry . in that case he has may 20 to come back
I am worried how long it may take to take care of his medical emergency.
Also - when the green card arrives, if I take it to him back home , does it help ?
I mean he can use the green card to come back ? That gives him couple extra months
