When you apply, if you are aware that a relevant ground of inadmissibility applies to you and you need a waiver to obtain TPS, please include a Form I-601, Application for Waiver of Grounds of Inadmissibility, with your TPS application package. However, you do not need to file a new Form I-601 for an incident that USCIS has already waived with a prior TPS application. USCIS may grant a waiver of certain inadmissibility grounds for humanitarian purposes, to assure family unity, or when it is in the public interest.
