1。 境外簽h4入境美國,到底有沒有i797
-No.
2. H1B 持有者換工作,有個新的i797,原來的h4需要一起更新嗎?-Not necessary unless the H-4 I-94 will expire soon.
主要我實在記不清h4有否延期過,因為我持h4在美國時間不超過3年,在第一個h4的有效期間內。-Check all of your I-94 duration to see whether there is a gap between the I-94s. If no, you are fine. By the way, USCIS only check your status from the date of your last entry. So, if you visited China after your spouse changed job, you don't need the H-4 approval notice before you reentered US.
