There are 8745 Indonesian descents that have registered in Southern Mindanao but only 2425 that finally registered as Indonesian descents. The author found out until this undergraduate thesis have been creating 1259 passports that have distributed to the Registered Indonesian Nationalities around Southern Mindanao, The Philippines. The Dilemma for the Registered Indonesian Nationalities mainly focused on the chain effect after they have owned the passport because they will face several adjustments after finally legally becoming Indonesian Citizenship. The Registered Indonesian Nationalities commonly approve and support the policy from the Indonesian Government to give them a passport. However, the dilemma apparently will come up after the passport get expired. Firstly, the Registered Indonesian descents commonly live below the poverty line and in the fact many of them that even cannot pay the Alien Certificate of Registration that cost P.160 as the document that they certified that they are foreigner that live in the Philippines. Compare to the price of passport that will cost them P.1500 per five years and work permit visa for workers that will cost them P. 8000 per year and additional P.3000 per year until five years. If the Registered Indonesian Nationalities cannot find the way to improve the amount of their income and they cannot find the way to pay the passport they will directly consider when they passport already become expired due to they will consider as the illegal migrants and will very vulnerable to get deportation to Indonesia.
