If your RP is still in process & not stamped on your Passport...You can leave anytime.But your new employer would have to arrange a work visa for you. You wont have to face the two years ban in that case. You can also come back on a family visa under your husband sponsorship if he (husband) fulfills the criteria set to have a family status by the Immigration Authorities. You can start working anywhere with NOC from your husband later on.
