The K-3 visa, also known as the Spouse Visa, is a type of immigrant visa category in the United States designed to expedite the entry of spouses of U.S. citizens into the country while they await the processing of their immigrant visa petitions. Here’s an overview of the K-3 Visa:

Purpose: The K-3 Visa is intended for spouses of U.S. citizens who are residing outside the United States and wish to join their U.S. citizen spouse in the United States while their immigrant visa petition is pending. It allows the spouse to enter the United States temporarily to await the processing of their immigrant visa.

Eligibility Criteria: To qualify for a K-3 Visa, the applicant must meet the following criteria:

1. – Be legally married to a U.S. citizen.
2. – Have a pending immigrant visa petition (Form) filed by the U.S. citizen spouse on       their behalf.
3. – Intend to reside in the United States with their U.S. citizen spouse once admitted.
4. – Meet the requirements for admissibility to the United States, including passing           medical examinations and security checks.

Duration: The K-3 Visa allows the foreign spouse to enter the United States for an initial period of two years, during which they can await the processing of their immigrant visa petition and apply for adjustment of status.

The specific requirements and procedures for obtaining a K-3 Visa may vary depending on individual circumstances and the policies of the U.S. embassy or consulate where the application is processed. It’s advisable to consult with an immigration attorney or review guidance provided by the U.S. Department of State for detailed information on the K-3 Visa application process.
