Dear all. I have just returned from the embassy after the interview. It went well and was mainly focused on my job responsibilities (i.e. visa officer wanted to confirm my eligibility for 1112). He also asked for original degree certificates and updated PCCs which I produced. On timeline, he mentioned that they would send around Medicals/ RPRF within 2 weeks. Then it takes them up to 1 month to assess the medicals once you have done them. Passport request thereafter. Visa stamping could take up to 4 weeks (but less if you live in the UK). In best case scenario, I could have visa stamped by May/June.
Basically, it was a really good experience. Just keep smiling and be confident.
Good luck to the rest.
