Non Immigration visitor visa - status: administrative processing


My wife applied for non-immigrant visitor visa to visit her sister in USA. We are at present in Austria. She was working earlier in India, but she is not working now and is staying as a dependent in Austria.

On the day of her interview she was asked to submit her CV, which she sent on the same day. Since then the status is the same, Administrative processing.

Not sure, why her CV was required when she used to work in the past and now we applied for a tourist visa.

Please suggest if there is anything which can be done to get some clarity on the application process.

Thank you.
