L1, L2 Visa

My L1B Blanket visa is approved. Thanks a lot for this forum and users who shared their questions and experiences.
Here is my share.

after a long wait for getting an appointment, I was able to book an appointment on Feb 7th. My biometrics was scheduled on Feb 18, 2022, and my visa interview was scheduled on March 1, 2022.

Biometrics was simple and straightforward. My appointment was at 8:00 am, below are the documents that I carried.

1. All passports, old and new
2. DS-160
3. Appointment letter
4. Visa application fees.

They scanned the passport and verified the details with DS-160 like name and other details. Post which fingerprint and photo were taken.

Interview day [March 1,2022]

Documents:
1. Passport
2. DS-160 (which is stamped previously at Biometrics)
3. All the documents shared by the company (I-129S, I-797) triplicates
4. All personal documents like marks card, experience letter of the previous org, offer letter, payslips, etc

My interview was scheduled at 8:30 am, I reached the venue around 8:10 am. There was a long line of people waiting for their turn to get inside. (Even 9 am slot candidates were let inside)
Once inside, I was asked to provide the latest passport, 2 copies of I-129S (all 8 pages), I-797 (Blanket L First page), and a Demand Draft for 500$, then they organized them in an order and asked me to wait.

I did not carry demand draft and paid using a credit card. I did take cash as well just to be on a safer side.

There were more than 15 people before me for Blanket L1.
