Cousin or Aunt details in DS 160?

[usvisitor1]

In case one has a cousin / aunt in the US, is it necessary to include their details in the DS 160 form? We are not going there to meet them, but to meet my elder brother and tourism.

Also, if I am going with my parents for interview and since they have retired, is it a good idea for me to stand between them and take the questions instead of my father leading the conversation? Since we are self sponsoring our trip and my father has retired, I don't want VO to spend a min asking questions to my father and without turning to me and reject our visa if they feel we are not financially strong.

My sal is 12L+ and I work for a US based MNC.

Lastly, along with invitation letter should my brother also send leave sanction letter from his company?

Just write AUNT under relatives other than immediate relatives.
It is not going to affect the outcome . One should be truthful.
If you omit it, and on later possible visa applications, you or someone in the family mentions it, it could create problems.

Just be natural , they will ask questions from each of you as they deem fit.

You will need your leave letter not your host's.
