The Trump administration has added seven countries, including five in Africa, to the list of nations whose passport holders are required to post bonds of up to $15,000 to apply for visas to enter the United States.

he State Department is proposing requiring applicants for business and tourist visas to post a bond of up to $15,000 to apply to enter the United States. It's a move that may make the process unaffordable for many.

It says the countries affected will be listed once the program takes effect.

The head of Homeland Security says travelers who aren't REAL ID compliant by the upcoming deadline this week will still be able to fly but should be prepared for extra scrutiny. Kristi Noem told a congressional panel that 81% of travelers already have IDs that comply with the REAL ID requirements.
