Anyone hiring within DMV (DC, Maryland, Virginia) area?

Hi everyone - I truly apologize if this is not the right place to ask this but my wife has degree in chemical engineering and has HACCP/SQF certification and over 4 years of experience as quality assurance manager at food manufacturing facilities and was looking to switch careers.

Her dream is to become an auditor or work in the food safety division within FDA or USDA, but unfortunately they require US Citizenship (she is a permanent resident/green card and won’t get her citizenship for at least ~10 months).

Apologies again if this is the wrong place to ask but it kinda makes me sad to see her not having too much success to find many openings around this area (and of course not even being eligible to work within the federal Government) and figured it never hurts to ask if anyone knew anything around this area.

She is currently at a consumer goods manufacturer and she does not hate it but she works pretty tough hours (almost 10-11 hours a day plus some weekends) and is responsible for much for than just quality assurance it seems. She really likes the people there but I think it is getting difficult for her to be responsible for many parts of the facility than just quality.

Appreciate all the help and leads (or just advices if there are any certifications you recommend her to get to become more competitive)
