Hi Willpower,
My printer here allows me to scan documents so I just put the passport flat at the page(s) with personal details & the one with observations & scanned.
The fee was $60.00 plus a couple of dollars admin (I did not print the page so do not have the exact amount)
The site says that you should expect a response in about 72 hours but I got my confirmation (in an e mail) in less than 24 hours.
The E Visa says I will be subject to a mandatory biometric check on arrival in India. Not an issue. I live on the Isle of Wight & the E Visa is a whole lot easier than possibly having had to treck all the way to London & back to apply in person....
Expect a bit of fun & games as, for example, you will be asked to give all countries visited in the last 10 years. Your answer will then probably be rejected as the box can seemingly only take 100 characters so just knock out a few until you get below 100!
Good luck.
Ian
