因為配偶在國內，雇主在申請H1延期的時候就不管H4了，我該如何給lz申請H4延期呢？
另外lz有用即將過期的H4申請的簽證，還在有效期，還用申請新的簽證嗎？用哪種辦法不會有問題呢？
1. 現有簽證，過期H4的表，H1延期的收據（估計到時候批件還下不來）
2. 現有簽證，H4延期的收據（H1延期的收據是不是也需要呢？）
3. 新簽證，H4延期收據。這裏有個問題，估計lz回來的時候H1延期還批不下來，用延期收據可不可以申請簽證？
-Have your old H1 status expired yet? If no, he/she can use your old H1 approval notice to apply for the H4 visa to come back or if he/she still has a valid H4 visa on his/her passport, she can use this visa and your old H1 approval notice to come back. Then, do the H4 extension using your new H1 extension approval notice (if approved) or using your H1 extension receipt (if still pending).
If your old H1 expired, he/she can not enter US until your H1 extenion s approval. Then, he/she can use your H1 approval to come back either applying for a new H4 vsa or using the old valid H4 visa.
He/her original H4 approval notice has been useless since he/she left US.
