B2 Visa while the invitee is in India

I want to apply for B2 visitor visa for my parents, and i myself will be using the drop box facility to get the stamping on my passport, my i 797 (H1B) is valid for 2 more years.and i am currently in US and traveling to india for vacation, while on vacation i want to take my parents to get the B2 Visa interview process.

my question is while my i-94 shows that I am out of USA , will there be any problem if invite my parents and apply for B2 visa for them.

It should be ok. Your parents can carry a letter from your employer stating that you are on an approved vacation, still employed with them and are expected to return on XXX date.
