If a Indian Citizen obtains a PAN as a Resident Indian Citizen, then migrates to a foreign country and becomes a citizen of that country, then after a long overseas stay returns back to India on a foreign passport and say 'OCI', will it impact his/her PAN that was obtained as Indian citizen?
Do expats have different PAN numbers?
Do such ex-Indian citizens who return with a foreign passport need to file “updation of PAN details” and give new documents? Does anything changes with respect to his PAN or everything remains as is?
