What should I do if family opposes my career?

I am a married woman currently studying and working part-time on a contract basis. I had come with my in-laws’ consent for my baby’s treatment, and now my visa will be valid again, so I plan to return to continue my education and work. However, my husband and his family are completely against this decision and are opposing my career. If I travel back alone to support myself, what steps should I take legally to protect myself and my rights? Please guide me on this matter.
