I have filed for H1 b visa with a company with which I am currently working but now want to discontinue, how much I need to pay

If you are in one of the licensed healthcare occupations that requires a VisaScreen certificate from a credentialing organization, such as a Physical Therapist or Speech Language Pathologist, then you may have a serious problem. Even if you were already working for this employer lawfully, such as being in F-1 OPT (student with authorized post-completion practical training), the H-1B petition must have been "approvable when filed." If the currently-pending petition requested a change of status to H-1B, and you were in the US already, then you would need to have had the VisaScreen or comparable certificate at the time the petition was filed, or it may be denied. If you were outside the US when the petition was filed, then a petition could be approved upon proof that you met all the requirements for state licensure, but you would need to have the VisaScreen in hand at the time you applied for the H-1B visa.
