Which we know is not true, due to dual citizenship allowance until children reach 18 years of age. But this guy is a police Brigadier General and doesn't know that...oh well.
It may be not a case of him not being aware of it, Dafluff, but a case of us having only partial information on and missing to read the fine prints and deduct from it.
First of all I would like to say that, as certainly anyone here, I find this case a real shame for Indonesia.
To better understand BrigJenPol Sembiring comment you have to keep in mind an important detail: her age. She is 16 and therefore is born in 2000, 6 years before the enactment of UU 12/2011 which has granted dual citizenship to kids born from a mixed marriage.
If kids born after August 1st, 2006 are said as being dual citizen, it is NOT AT ALL the same for those born prior to August 1st, 2006, like one of my kid and like Gloria. These kids were born foreigner if their father was foreigner and at the enactment of UU 6/2011 they did NOT become automatically dual citizen.
Concerning Theo, my son, I had to process his naturalization, and to do so there was a time limit (August 1st, 2009 as per UU 12/2006). Many parents of kids born prior to August 2006 were not aware of this time limit. Others already managed to get an Indonesian passport (obviously by dodgy means) and then were screwed when the law took force and were unable to register the dual citizenship of their kids because he/she was already a citizen, at least officially if not legally...etc.
Sometimes the kid was Indonesian by law (parents not being married and therefore kids not having officially a father, allowing him her to be WNI) but the parents managed to get the father's citizenship to the kid through the father's country of origin embassy. This defacto dual citizenship was illegal under Indonesian law and many parents when the new citizenship came to force were afraid to be in trouble and therefore didn't legalized the situation.
Just around me, I know quite a few kids of Gloria's age whose dual citizenship or even sole Indonesian citizenship is dodgy and could be challenged legally.
There is in fact quite a few possibilities to explain BrigJenPol Sembiring's words. He may well talk out of his ass, but it also could easily could be that, as for many kids of Gloria's age, her dual citizenship has not been properly registered.
What I want to say you Dafluff, is that when you have a kid born prior to August 2006, there is no such thing as an automatic dual citizenship allowance until children reach 18 years of age. It had to be processed, and many kids have been left out of the procedure for a wide array of reasons.
