I wanted to go for the K3 because that be faster. What should I be preparing for K3 interview?
Check out Packet 3 and Packet 4. Also it varies from embassy to embassy in India.
Chennai does not send you packet 3. It straight sends you Packet 4 along with the interview letter. Mumbai sends you packet 3. After you submit your packet 3, they'll send you packet 4 and the interview date.
You can star working on the following:
1. Get the local police clearance certificate. (no need for the interview letter)
2. Get the RPO Police clearance certificate (may require interview letter, I know Bangalore RPO requires it).
2a. If the visa applicant has resided in a foreign country for periods of 1 yr or more after the age of 16, need police clearance certs. from those places as well.
3. I-134 notarized (to be signed by the petitioner, supporting documents are also required depending upon if you are self-employed or employed).
3a. Employer letter
3b. Bank statement
4. Marriage certificate (am sure you already have this one)
5. Birth certificate of the beneficiary (original in English or translated)
6. Tax returns for last year. (1040 and W-2)
7. Copy of Natz. cert. (if it applies to you) and copy of US Passport.
8. Divorce decree(s). etc (if applicable)
9. Evidence of relationship (photos of engagement, ,arriage together with family etc. emails letters and the kitchen sink :-))
If possible send USD 100 cash, this will be accepted at the embassy as processing fees for the visa.
Medical exam is also required from the US consulate approved doctors, but can't do it without the interview letter.
