Has anyone traveled to US via Delhi airport without having any exit stamp from Nepal (TIA airport).
Any potential issues that one might run into while doing this. I am travelling to USA via UAE, would i be required to produce no objection letter?

Please share your experience.

Thanks in advance

Please see the news link below regarding No objection letter:

In my opinion if your travel record shows that you have only travelled to India then there is no sense that you need no objection letter (NOL) from Nepal. Just fly peacefully from India to USA. Good luck!
