Is it possible for me to work outside the US (for the same company that I work for now) while on green card? My company has an office in India, and I have to travel to India for family reasons. I was planning to work in India for some time, and then come back in about a year and half and apply for citizenship. I have lived in the US for about 3 years on my green card now.
It is possible. Look into both I-131and N-470 filing through a lawyer.
