The "Protect Patriot Spouses Act" seeks to streamline the immigration process for spouses of United States citizens who are currently serving or have honorably served in the U.S. Armed Forces, including reserve components. It amends the Immigration and Nationality Act to allow these eligible spouses to adjust their status to lawful permanent residents, even if they were not formally inspected and admitted into the country. The legislation waives certain grounds of inadmissibility, such as those related to unlawful presence or previous removal, and grants the Secretary of Homeland Security discretion to waive others, including certain misrepresentations or minor criminal offenses, provided the alien does not pose a public threat. This aims to remove common barriers that prevent military families from remaining together in the United States. Furthermore, the bill establishes a mechanism for eligible military spouses who were previously removed or voluntarily departed from the U.S. to apply for immigrant visas from outside the country. It also mandates a program allowing these individuals to enter the United States as nonimmigrants to reunite with their citizen spouses while their applications for adjustment of status are being processed, with similar discretionary waivers for inadmissibility grounds.
