True that the Temporary Restraining Order (TRO) did not affect the entire Executive Order.

Not true that it only affects green card holders & residents that already have a foothold in USA, and refugees.

This part of the Executive Order was also affected by the TRO:
"section 3(c) of the Executive Order suspends for 90 days the entry of aliens from seven countries: Iraq, Iran, Libya, Somalia, Sudan, Syria, and Yemen."

As the Court of Appeals wrote: 
"we decline to limit the scope of the TRO to lawful permanent residents and the additional category more recently suggested by the Government, in its reply memorandum, “previously admitted aliens who are temporarily abroad now or who wish to travel and return to the United States in the future.”"
