I am a US citizen hoping to visit India for a week in October, and according to the Internet there are multiple options to go about for the VISA route, but the online one seems the simplest. However, it costs a decent bit, so I want to make sure I'm doing things right before applying. Do I need to have my plane ticket squared away for sure before I apply? Is it a big deal if I'm not sure the exact dates I will be there (I'd only be off by a day or two). Anything else I should be aware of? Thank you!
Since April 2019, the India e-Tourist and e-Business visas are now valid for one year and for multiple entries. You need to apply at least four days before your expected date of arrival. You'll need return or onward tickets out of India, but you don't have to buy them before applying for the e-visa. If you aren't sure when you will arrive, you should put down the earliest possible date you think you might arrive.
