Can I use my B1/B2 even if issued by old employee?

[jemmlove12]

Hello,

So I have just realised I have in my passport a C1/D visa and a B1/2 visa (both valid until 2024) for my time with emirates. I am no longer an employee of Emirates airline.

My question - Can I still enter the states on the B1/2 visa and how long will I be able to stay for?
