I went here for my US Visa Renewal with 12:45 PM appointment slot. I made it to the drop off counter only at 2:45 PM. At 12 PM, the people with 11:45 PM appointments were still waiting in the queue outside the building. So everyone else is made to wait opposite the building on a dusty footpath with only a few trees for shade. I would think the least that can be provided is a decent waiting area. The security guards announce the slot timings on a megaphone that you may or may not hear thanks to all the chaos of people and autos and cabs. Not sure why this is the chosen way to communicate to people especially in this age of technology. Then you queue up outside the building and wait to be let inside. Once inside, you stand in a queue in a narrow, stuffy corridor and wait to be let inside the room. Then you queue up and wait for a counter to free up to finally submit everything. From here on out, if you’ve got everything in place, you’ll be done in 10 minutes. Take the day off so you can dedicate it to this hellish experience. Carry a cap and sunglasses and water and snacks. I really hope they improve the way things are done. But it looks like we’re asking for too much. (One star for the guards who are very helpful and organized. One star for the lady at my counter who was pleasant and quick.)
