1，请问老师，485批准信收到后，给孩子到领事馆办签证还是旅行证？因为要再次打指纹才能收到绿卡，约了infopass去给护照上盖绿卡印章，如果盖完印章后，给孩子办签证，还是旅行证？
-I think your child should apply for the Chinese visa, not 旅行证.
2，请问老师，我的护照只有5个月有效期，可以到当地移民局盖绿卡印章嘛？
-Yes.
盖完绿卡印章后，如果到领事馆或是回国换完护照，还可以用这个旧护照上的绿卡印章和新的护照一起使用回到美国嘛？
-If you want to renew your passport in US before you leave, I would suggest you to do it first and then, use the new passport to get the green card stamp. Otherwise, you of course can use the old void passport which has green card stamp and the new passport together for the travel.
