I sent an email to them asking about address proof as I didn’t have one for India. They asked me to submit a proof for non-Indian address. I uploaded all the docs online and got conditional approval with a reference number within 72 hours. I flew into BLR on Sunday, went to the BoI counter and asked them for biometrics. They took it next to one of the foreigner arrival counters. The BoI official pointed out the under construction e-gates, stating they will be ready in the next few months. I got my approval today, with validity of 5 years. Hoping to use it on the next travel back to India.
