I have a question , my dad already has a visa tourist 10 years he came to visit me once at USA ,I applied for a green card form him when he was in Morocco , he had his interview on 10 February and because of the pause they didn’t issue his visa , my question is can he come visit me in USA with that visa tourist that he has and stay with me less than 6 months until the pause is lifted ?? Thank you
