Thank you for your replying appreciate that . What kind of visa did you applied? What is your online application right now?Yes. Security will check if your name is on the list of appointments that they have. Even if you have a minor child, make sure you have an appointment for them. Otherwise, be prepared to stand in the queue.
We submitted surrender and visa application at the same time on the same appointment. The catch was that 5 of us surrendered passports, but only 2 applied for a visa so they were ok with it. If all 5 were applying not sure if the situation would have been any different. I have never detested any Indian office more than BLS. They are just terrible.
