Indian tourist visa processing time ?

Hello, I have been granted British nationality recently and got surrender certificate, applied for renunciation and still waiting for it.

Meanwhile me and my family have to travel to India by january end, we ideally want to go to surat airport which is not included in e-visa airport. If we get stamped visa can we travel to that airport ? Also how long is processing time for stamped tourist visa for India in London,UK.

If I recall correctly, there are no international direct flights to Surat. Most take you to Delhi and connect you to a local flight from there.

In which case, you can select Delhi for eVisa and get your entry stamped at immigration there before proceeding to Surat domestic flight.
