I came to USA as L2 with my spouse, after leaving my job. Now my parent company is asking me to take up their assignment based at USA. and also asking me to confirm the possibility of starting their office at States. Is these possible? at least working for them is possible. I have my EAD. Can I work and take salary from outside USA firm?
Once you have the EAD you can work for anyone in USA, including a company that is not in USA.
