I am recently going through all the process of resident visa sponsored by my husband...its not that complicated...
once u get the docs from sponsor in Saudia, you need to go to GAMCa, they will suggest a medical lab to which u can visit that day. u also dont have to book any appointment.. if u ask the lab for tcs, they will deliver report within three days at ur doorstep as they did mine. then book an online appointment with etimad separately for each member whose visa is needed. then go to etimad, they will proceed all the docs same day. I submitted my docs on 21st april and today it shows that its under process in embassy. I hope it will get stamped this week..
