The United States is considering adding four countries to its visa waiver program for a stay of up to 90 days, Reuters reported.

“We have four candidates in the pipeline: Israel, Cyprus, Bulgaria and Romania”, said U.S. Homeland Security Secretary Alejandro Mayorkas on Tuesday.

This means Moldovans with Romanian citizenship, too, could soon be able to travel to the United States without visas.

In September, the United States added Croatia to the visa waiver program.

There are currently 40 countries in the program. To participate in the program, a country must meet requirements related to counterterrorism, law enforcement, immigration enforcement, document security, and border management. The requirements include having a rate of nonimmigrant visa refusals below 3%, issuing secure travel documents, and working closely with U.S. law enforcement and counterterrorism authorities

There are over 642,000 people in Moldova who hold Romanian citizenship.
