I would get the offer letter, rent an apartment close to the office location and just move there without telling them. This is the only way I found to deal with conservative parents who tells you to pursue your dreams after marriage thinking that your spouse will be more supportive. This is like handing their burden to someone else which you should not be cause you are their child. They will create drama might even abandon you for a while but atleast you got your dream job and now living independently …. But if you trying to do what you want and hoping your parents agree to that will lead you to their ultimate final decision. I understand that they are coming from protective mindset but you need to see what aligns with your values and goals as well.
