FINALLY, got my wife's visa.
It took me exactly 15 days from applying for the visa to receiving the visa.
Though the sms from metrash said i could print the visa online from the website, I could not do so, as the website didnt allow me to do so.
So I had to personally visit the MOI office Gate 4 ground floor and wait for almost 2 hours to finally get a print copy of the visa.
