On April 22, 2020, Trump issued his new green card travel ban, effective for 60 days (with possible extensions).  It does not apply to:

• EB-5 investor immigrants
• People in the U.S. applying for permanent residence via adjustment of status
• Spouses and children under 21 of U.S. citizens
• Green card holders returning to the U.S.
• People issued valid immigrant visas who have not yet arrived in the U.S.
• People seeking to enter the U.S. with an immigrant visa as a physician, nurse, or other healthcare professional; to perform medical research or other research intended to combat the spread of COVID-19; or to perform work essential to combatting, recovering from, or otherwise alleviating the effects of the COVID-19 outbreak
• People whose entry would further important U.S. law enforcement objectives
• Any member of the U.S. Armed Forces and any spouse and children of a member of the U.S. Armed Forces
• Any person whose entry would be in the national interest, as determined by the American consul or USCIS

The American consul has discretion to determine whether the immigrant is eligible for one of the above exceptions.

The new immigration ban principally pauses immigration via American consulates overseas for parents of U.S. citizens; spouses and children of U.S. green card holders; employment based 1st, 2nd, 3rd and 4th preference immigrants, as well as green card lottery winners applying for immigrant visas.

Stay safe, and carry on.
