is it possible to apply immigration visa thru internet?

Answer 1

you can begin the process online for many countries. but you will still need to send a hard-copy application with all your documentation and go to an interview (or two). again, it depends on the country, check www.uscis.gov or with your local embassy.

Answer 2

You can apply for the Diversity Visa Lottery by internet - in fact, that's the only way you can apply. For all other categories of immigration, no.

Answer 3

Nope, but you can print the forms from www.uscis.gov and turn them in for approval.
