My first post on the TT was a silly question I asked on the India forum way back in 2008.

I am a holder of a Canadian passport, Can I get my India visa from one the countries that share the border with India?
If you are planning to arrive by air, you can apply for your e-Visa anywhere.
https://indianvisaonline.gov.in/evisa/tvoa.html 12 months, multiple entry, any stay to a maximum of 180 days
If you are at home, you could get a 10 years visa

You could apply for an Indian visa from Nepal / Bangladesh / Pakistan - your experience will be smoothest in Nepal.
