DEL has about 6 dedicated counters doing nothing but eVOA. 9pm is the quiet time in DEL, it gets really busy at 11pm onward.

Family Immigration with Visa holder
 

Sharing some additional immigration experience. After landing and heading to an ad-hoc counter thinking it being an information helpdesk, the person indicated he could process the ETV visa for the baby (no one was ahead of us). ETV visa was just a stamp with expiry date.
Our (Indian nationality) immigration had to be done at different counter (normal lines). We gave our passports (which the officer processed) and also gave him babies US passport. Without opening US passport Officer indicated he can't process it. He was not sure of processing hers and then later checking with his colleague indicated nothing needs to be done since visa was already stamped for hers in the passport. We were good to go.

So basically once you get the visa nothing needs to be done (for family travelers with infants having different nationality).
(Would have been ideal if the officer who gave ETV also had processed our immigration. Not sure if it was due to our ETV being processed at a side counter at the entrance instead of main section where there were queues)

On the other hand, if you are not absolutely accurate with your data you might get turned back and refused admission to India. To wit:

Two friends of mine (US passport holders with ETAs were going to India via AA and CX Business Class SMF-LAX-HKG-DEL for touring in Rajasthan last week. They made it through docs checks, etc. at SMF, LAX and HKG.

When they arrived st DEL, it turned out one digit in one friend's passport was transposed with another on the ETA forms. They were detained at DEL immigration and she was not allowed to remain in India (nor was her husband allowed to recover her baggage). She requested to submit another eVisacrequest, but she was told she had to depart India to do so, as it required 24-72 hours to process and she could not remain in India for more than 24 hours and must leave.

After a lot of palaver by several immigration staff and supervisors a CX ground staffer came and fetched her forbthevreturn flight to HKG. She was escorted to the aircraft and seated - CX was forced to hold the flight for her and was held well over an hour past scheduled departure. (Her husband received his visa and remained in India.)

At HKG, she was processed and out on the next LAX flight. During all this time, CX staff had her passport - they declined to relinquish it to her until she was off the aircraft at LAX, where it was returned to her. Even when she requested to visit the lounge to shower and freshen up, she was escorted to the lounge, and her passport was retained by CX personnel.

Yep, her error, but also one by AA staff when they checked her in at SMF, and Cathay staff in LAX and once again at HKG. As she arrived in DEL on CX, CX had the responsibility of flying her out - and is subject to a significant fine for allowing her to board with faulty documents. And of course it was a very costly lesson for my friends (most insurance will not cover this kind of event, AFAIK).

So be a bit obsessive when you apply for the ETA, regardless of where you're going - but in India, bureaucracy can be demanding and inflexible if everything is not just right.

compare it
 

ha ha when its India, its bureaucracy, when it happens at US airports it will be immigration rules (just imagine and compare so called 'flexibility' to US immigration, then name a country for its bureaucracy) :)
(different matter that being India one would have expected leniency, however guess not)

How can you not be accurate with entering info? The passport is scanned and uploaded, right?
I found the list of question they ask. Seems like many are completely irrelvant to a tourism visit: the birthplace of my father??
Also, I hear there are endless problems with the payment system: page no loading, card declined, etc.

Would appreciate advice
 

I have questions about a few matters re the Evisa applications for my wife and myself. They may be so minor that I'm unnecessarily concerned about them. But knowing how Indian bureaucracy can be, I'll pose them anyway:

1. The application asks for a "reference name" and address and phone in India. Am I correct in assuming that simply providing a hotel name is sufficient? I do happen to have a couple of folks whose names I can provide, but would much rather just go the hotel route if possible.
2. The application also asks for the countries we've visited over the past ten years. The number of those countries far exceed the limited space in the application. Is it ok to just provide a few names,l even though our passports indicate more?
3. The passport asks for expected "port of exit from India." Since we're still finalizing that leg of our trip, am I correct in assuming that we can end up departing from a different one from the one we identify on the application?
4. The application provides size limits in terms 300KB for the passport page and 1 MB for the photo. Are these strictly enforced? It looks like my passport PDF goes over the 300KB limit.

Thanks for any help!

Give the last 10 countries, mention the name of someone you know and scan the passport in a lower resolution.

Size of photo
 

Should be fine. Exit port doesn't matter much, and as such no rule that it needs to be fixed/same (unlike entry port)

Try some photo editor software that reduces file size, if lower resolution scan is not possible.

India BUSINESS visa
 

Please suggest an agency to use for a business visa. I've submitted 4 photos to CIBT and keep getting the same generic rejection email. Face needs to have neutral expression, white background, no shadows, space above head, part of shoulders included. My last photo satisfies all this, but was still rejected. I'm about ready to submit a picture of my ... next!

Thanks to both of you for your help!

My sympathies. The process is a real PITA. After a couple of glitches with trying to apply online (not even getting to the submission state) for tourist visas, I used a company I've used frequently in the past, Travel Document Systems https://www.traveldocs.com/

I recommend them with mixed emotions. On the one hand, I did get tourisrt visas for wife wife and myself through them.And their form was somewhat simpler and easier to pay for (simply using a credit card) than the official form. On the other, I had to nudge them to follow up, despite the fact that I was paying for expedited 24-hour service. But they're honest and I supposed better than nothing.

Hope it all works out.

My 10 year visa is expiring soon, and I don't have a surrender certificate (yet). Is the e-visa option available to former Indian citizens with current US citizenship?

Should be no problem.

So, what is the deal with the photo, are you scanning a passport photo, are you taking a new one yourself, or via a professional agency, or what?

I did it for myself, spouse, friend. Just used the photos we had for USA passports but edited to meet their specs and it worked fine.

Take a selfie of yourself in front of a white wall, size it, upload it, done.
