WASHINGTON, Aug. 5 (Xinhua) -- U.S. President Donald Trump's administration will first require visa applicants from Zambia and Malawi, two African countries, to pay bonds of up to 15,000 U.S. dollars for some tourist and business visas, the State Department said on Tuesday.

"Starting August 20, 2025, any citizen or national traveling on a passport issued by one of these countries who is found otherwise eligible for a B1/B2 visa must post a bond in amounts of 5,000, 10,000, or 15,000 U.S. dollars, determined at time of visa interview," the State Department said in a notice on its website.

This requirement is part of a pilot program scheduled to begin Aug. 20 and last until Aug. 5, 2026. It will apply to nationals from certain foreign countries applying for B-1 or B-2 visas for business or tourist travel to the United States. These visas usually allow for a maximum stay of six months, though extensions are permitted in some cases.

The list of countries may be amended throughout the program, according to the notice.

"This requirement applies regardless of place of application," said the notice, adding that "a bond does not guarantee visa issuance, and if any individual pays fees without being directed to do so by a consular officer, that money will not be returned."
