我們自己填表I-539, 那麽孩子無論跟老公或跟我都可以?
-Yes.
孩子還必須到USCIS office嗎?
-No. I-539 has to be filed to USCIS. Read I-539 Instructions. But as I said, if your H-1 has been effective (check your H-1 approval notice for the effective date), his TD has been void, and thus he can not file I-539 to change TD to H-4 within US, and he has to go to the US-Canada border or US-Mexico border to get the H-4 I-94/status.
