President Donald Trump may expand his controversial travel ban with an announcement expected as early as Monday, the three-year anniversary of the original order, which targeted several majority-Muslim nations.

The list of countries is not yet final and could be changed, but nations under consideration for new restrictions include Belarus, Myanmar (also known as Burma), Eritrea, Kyrgyzstan, Nigeria, Sudan and Tanzania, according to two people familiar with the matter.

A draft being considered by the Trump administration would place immigration restrictions on the additional seven countries, but not necessarily completely ban all citizens of those nations from entering the United States. The restrictions could apply only to certain government officials, for instance, or certain types of visas.
