I was and am holding a lower position like research technologist. Company applied perm several years ago for me and I got my greencard and I still hold the old position title. In perm application form, the position they put here was a higer position like research associate.
My question is:
does the company has the obiligation to offer me the higher position
-No. If you are not happy to work for them, you may just leave.
or it is optional to them by law, after my greencard was approved?
