according to the last notes ( everything was done except the security screening it was started on 12 april)
Security screening take already very long time, i will highly appreciate if somebody can advice how long usually it takes, and is there anything we can do if we cross the 6 month. ( i am from war country, and i have very long history of travel (3 times to USA, most of European countries and some countries more than 6 -7 times, and most of Asian countries).
thanks
