Hi,
We were in Bacolod immigration office on January 2. I was complying with annual reporting. My wife, Donna, is dual citizen too. The immigration officer did not mentioned any ARC-I card for my wife. When you went there, may be the officer was a mixing a little bit...
What is true is that a Filipino national should get a resident certificate from the city hall. It should be renewed yearly. We renewed it last week for 25 PHP. The only time Donna has been asked to show this certificate was when she applied for the building permit of our home.
We passed the immigration yesterday in Manila while flying back to Taipei. Donna and Charlotte both showed their Filipino and French passports and were not asked for ARC-I card.
Hoping it helps,
Regards,
Jean-Marc
