Question: a person from Africa got asylum in the U.S.and he is waiting for his green card. He has to travel to pick up his son in a neighboring country in Africa. (he is not returning to HIS country of origin) He has a refugee passport (the one from the United nations, with the blue cover). Will he be able to re-enter without hassle? he will be returning with his son who has a visa available at the embassy in that neighboring country. Does he need any kind of other permission? It might just be that this blue passport is called some I-XXX and I don't know about it. is it the I 131 people are talking about? thanks for input.
