Re: Swiss driving license
There are literally thousands of posts on EF on the subject of obtaining a Swiss driving licence. Yes, your country of origin (of your current licence) does matter, and no, Indian licences can't be exchanged for Swiss licences as US/EU/Australian/NZ etc licences can.
The OP's question (diplomatic status) is unusual. I suggest contacting your local Strassenverkehrsamt or whatever it's called where you live (motor registry).
