您好!我和兒子時綠卡,在美國居住。我先生暫時還沒有申請綠卡,人在中國,持有B簽證十年簽。疫情以來,B簽證不能直接入境美國,需要在第三國提留14天,但作為綠卡配偶又是可以直接入境的,請問,我先生在入境時需要準備哪些材料可以順利過關?
-He had better bring your marriage certificate and the copy of your green card. Also, he needs to show that he will return to China after the short visit, e.g. prove his connecttion with China (employment, etc.)
非常感謝!
