回复：我现在是H1，老婆是F1，合同明年2月到期，我现在申请

Your status will is OK during F1 pending. However, you need to register with school after your H1 expires. Your information need to be in SEVIS, otherwise your F1 may be denied in case F1 is still pending after your H1 expires. However in most cases, your F1 will be approved before next February.
