hi my wife is a beautician expert and she is curently working in a beautician parlour. she is in F-1 status. her employer is ready to file her green card but the question is how can we do that. is it possible for filing EB 3 or EB 4. also can we file H1-B from this employer because she would be graduating soon? is there any way for getting green card? and also how long would that might take?

any help from immigation expert would be grateful. looking for your response.

Thank you
