Washington (CNN) The Trump administration drafted plans to renew and expand its travel ban list to include immigration restrictions on seven additional countries, according to sources familiar with the process.

Unlike the travel restrictions currently in place, the new rules could limit certain immigrant visas from the additional countries, said a US government official -- essentially creating a partial immigration ban.

Not all of the restrictions are uniform, said the official, adding that the proposal limits some immigrant visas from one country and other visas from another.

The plans, which are still under review, are based on interagency input from the departments of Homeland Security and State, as well as the White House, according to the official. President Donald Trump will make the final decision on changes to the ban.

In an interview with the Wall Street Journal Tuesday, Trump confirmed that he is planning to add additional nations to the travel ban, but wouldn't reveal which countries would be added to the updated version.
