If my I-601A provisional waiver application is denied, would I still be eligible to apply for an I-601 hardship waiver under regular processing?
 
Yes, in many cases. If a foreign national’s I-601A provisional waiver application is denied, the foreign national may still be eligible to apply for an I-601 waiver under the regular processing. For example, if the I-601A was denied because the foreign national has another waivable ground of inadmissibility other than the 212(a)(9)(B) unlawful presence bar, they would still be eligible to apply for an I-601, along with whatever other waiver may be required, after being denied at the visa interview at the consular post abroad. Additionally, if the I-601A was denied because there was not a sufficient showing of hardship to the US citizen qualifying relative, but the foreign national also has a Permanent Resident qualifying relative that would suffer extreme hardship, the foreign national might want to apply under the I-601 waiver regular processing, which would allow USCIS to take into consideration the hardship to the permanent resident spouse or parent along with the hardship of the US citizen’s hardship.
