回複：家中急事. H1/H4 Transfer已交但未批，H4可以回國用原來的H1返簽嗎？

If your H-1b transfer is approved prior to her visa application, everything is fine. Otherwise if your previous H-1b is still valid, she may get an H-4 visa and be admitted, however there is little chance that her visa is denied or she is not admitted when it is noticed your H-1b is pending in system.
