ഞാന്‍ നിങ്ങളെപ്പോലെ ഒരു ദാരിദ്ര്യം പിടിച്ച പ്രവാസിയൊന്നുമല്ല.
നാട്ടില്‍ കാര്‍ന്നോന്മാര്‍ സമ്പാദിച്ച് വച്ച മുതലുണ്ട്.
പിന്നെ താനെന്താ ഇവിടെ , ഭാര്യയേയും കുഞ്ഞുങ്ങളേയും പിരിഞ്ഞ് ..

There are basically two types of NRIs (Non Resident Indians)
One: Never Returning Indians
Two: Not Required Indians.
The first category is the rich NRIs who settle elsewhere, mainly in European and American countries. They enjoy their life in their living countries and never bother to send money to the family ('coz the whole family is living there!!!).They never return to India. So they are offered Overseas Citizenship. Let them enjoy Indian citizenship elsewhere and be a proud Indian.
