What you need to know about Nonimmigrant Visa Waivers
In recent years, many consular posts implemented an interview waiver procedure that allows certain nonimmigrant visa applicants to obtain a visa without an in-person interview. Due to the COVID-19 pandemic, this interview waiver process has been implemented more broadly at consular posts around the world and the requirements to qualify have been expanded.
It is a great way to renew visas in the same nonimmigrant category saving time and resources in preparation for the in-person interview with a consular officer.
