Here is the letter that you will receive from Mumbai Embassy. Read it over carefully and follow the instructions. Another member of VJ added some additional information contained below which outlines what he experienced. https://drive.google.com/file/d/1xukUjdqnKM7yqrkqfPfl8tCao_BY2XsC/view?usp=sharing https://photos.state.gov/libraries/mumbai/1057584/senkx/BMB IV Packet 4 for Ks January 2015 Revision_001.pdf Once you received your case number from NVC,  I would recommend you fill out DS-160 form and submit. Some say the packet 3 letter is nothing just waste of time same thing they have mention which you easily get from USCIS website when you called to the clinics to book your medical appointment date they will ask you have you received your packet letter or not. Just say yes and booked the appointment date however you will receive that letter within 2 weeks the day you will get your NVC number. Go on USCIS website make your account with password and then pay your fees to Citibank or Axis bank. They will give you reference number. With that number you can book your biometric and interview appointment date. The fees are 18,500 and for medical but I recommend that you carry 20,000 with you in the event you need more. Be sure to  keep at least 7 days gap between medical and interview.
