hey Abhayshreshtha,

sorry it was Jan 7.

You got to fill ds-156 and ds -157 , You can fill up online but will have to submit the hardcopy. There are shops outside nabil who fills up the form for 150 Nrs. But i filled mine on my own, cost me 20 Nrs.

Here you will find the forms, fill it up and print it
