Visitor visa for sisters family

[Swati123]

Can some one please help us? For visitor visa for my sister and her family, what additional documents she needs to carry? They both are govt doctors. They are coming here to attend my brother's wedding in US.

Valid original passport. ...
One photograph as per specification. ...
DS160 US Visa application confirmation page stamped at the Visa Application Center (VAC).
Proof of fee payment, which is a valid receipt.
ADDITIONAL DOCUMENTS:

1. Income tax as prepared by a CA

2. Property papers

3. salary slip for 3 months

4. invitation letter from US family for thewedding

5. bank statements, PAN id

6. wedding invitation card

They are both entering as SELF to pay for their trip. -- Is that ok? They both make 50K per month each, so total 1 lakh. Do I need to fill form 134 for them?

They are not getting the vacation letter from govt - they will do it once they get the visa. -- is that ok?

Should they use Adhar number as the national identification number?

In their passport, state/province is not listed. Only the city is there. Should we leave the state as blank in the form?

do we need to provide 10th class education details as well?



I appreciate your comments. thank you.....
