I am a chiropractic doctor with H1B and I am considering to apply for the green card based on employment. I want to ask usually how much it would cost for the whole procedure? What is the minimum salary for chiropractic in CA (LA) to be qualified for applying the green card?

Thanks.

Your salary should be at least the same figure as approved by DOL. You can check for the fees here: USCIS - Immigration Forms
