Have you applied for an Indian passport as a foreigner with a much?
You can get back to India after a lifetime abroad. Earlier, MEA used to trouble returnees. Sushma made life easier for returnees. OCI card makes giving up foreign citizenship immaterial. US and Canada offers huge social Security benefits. In spite of that some people come back post retirement to take care of parents. Earlier, there were restrictions on investments in all asset classes for such people. Some of these restrictions have been relaxed now. World has become global now. Many naturalised Indians have come back and taken up jobs in India. Then gone back again. There are compromises to be made. Expectations to be callibrated. It's not a big problem.
