Hello,

H4 Visa approved with a note on Visa page NIE UNDER P.P. ON RISK TO LABOR MARKET. Does this mean H4 visa holder cannot travel or this is a just a note for approval?

NIE stands for National Interest Exception
P.P. stands for Presidential Proclamation

Your visa is valid for travel to the US

H1B Visa approved with a note NIE UNDER P.P. ON RISK TO LABOR MARKET

Is there any 30 days travel rule of flying back from date of H1B VISA issued, for example H1B VISA issued on 23rd Sep flying to USA on 27th Oct ?
