聽說30天內是automatic revalidation.
-Yes for going to Canada or Mexico.
請問哪位知道此規定的官方網頁？
-Google "visa automatic revalidation" and you will find a lot of information.
我們是去加拿大登陸（短登），打算從美國這邊出去的時候就說是去度假，會有什麽問題嗎？
-No.
有沒有什麽特別需要注意的？
-Bring your h1 approval notice with the H1 I-94, recent 3 month paycheck stubs and passport. Don't surrender your I-94 to the airlines or US Customs when you leave US because you need it to return to US.
再謝！
