请教8老师，我持加拿大护照，以H4签证在美国，这二天要回国一趟，这种情况，回美国时有没有问题？-Fine.
还是要在国内的美国使馆重新签一次？-No visa needed for Canadian citizen. Just show your passport, your marriage certificate, your spouse' H-1 approval notice and his/her latest 3 months paycheck stubs to the CBP officer at the port of entry, and tell the officer that you need H-4 status to enter and stay in US when you return to US. Then, the officer will stamp your passport and that is all.
另外，如果要重新签的话，需要带些什么材料回去？
