My wife got FTJ IV visa stamped in her passport in Chennai. EB3 - PD 4/30/2001.
Below is the process, in her words, she went thru:
Medicals:
Called two days ahead for a 10.00 AM appointment with "Lister METROPOLIS Laboratory Research Center Pvt. Ltd" and a 4.00 PM appointment with "Dr. Mathai Thomas".
Flew in from Hyderabad to Chennai, had in-flight breakfast, took a taxi from airport to the Lab, 30 min ride.
If anyone's interested: I had an appointment today for H1B visa revalidation. Overall it was a smooth experience. I was asked for my paystubs though.
Degree etc was not asked for. Total interview time was 2 minutes. The only question I was asked was whether I am working for the same company for which I had received an H1 visa previously. In my case that holds true. I also had an F1 visa previously. US Degree.
