比如我妈妈2018年9月回来美国，我可以在她一回来后再次帮她提交回美纸申请吗？-Yes. Enclosed the unexpired reentry permit (old one) with the I-131 filing.
8老师 是把回美纸原件跟着新的申请一起递交出去吗？
-Right if it does not expire yet when you apply for a new reentery permit by filing I-131. If it expired when you file I-131 for revewal, you do not need to return the expired reentry permit.
