@priyankasumitNS takes 3-4 months. But NS request so much paperwork again and again from employer. So your employer has to be proactive in replying in emails. Its better just check with employer every monday, so that they may reply in next week.
Congratulations!!!
This is great!!!
I am based in UAE still waiting for my endorsement letter and would appreciate your complete timeline along with how to fill up the forms.
