** LEGAL UPDATE **
This will affect an estimated nearly 1,500 Yemeni TPS holders who are already here in the United States and who arrived before January of 2017. For now, they need not return to Yemen unless they want to. (Yemen was initially designated for TPS in 2015, based on armed conflict there.)
Critics note, however, that the extension does nothing to protect people who later fled from the humanitarian crisis in Yemen, which is ongoing.
Instructions for registering and extending one's work permit (EAD) are yet to come from U.S. Citizenship and Immigration Services (USCIS). Check for the latest on its TPS Yemen page.
Effective Date: January 3, 2020
