Is F1 to H4 Visa Stamping in Mexico is allowed

Hi, I want to know can I my wife visit Mexico for H4 visa stamping if currently she is on F1 visa but she doesn’t have F1 stamp on her passport. Her previous stamp is H4 which she got in India. She applied for COS from H4 to F1 during her studies. She graduated last year.

So I want to know can she visit Mexico for H4 visa stamp when currently she is on F1 visa.

Thanks

She should be able to get H4 visa stamp in Mexico.
