I got an interesting question from Romeo today.
Here is Romeo’s e-mail:
Hello Romeo, thank you for writing with your interesting topic.
The answer to your question is quite simple. In short.. yes, with one exception. A dual citizen can indeed run for political office in the Philippines, except for the office of President.
So, Romeo, are you thinking of running for office?
Addendum: Upon further research, based on an offline discussion with Ron Speers (who commented below), I found that my answer is not 100% correct. Under the Philippine Dual Citizen law, if a Philippine Dual Citizen wishes to run for political office in the Philippines, at the time that he files his CoC, he must renounce his foreign citizenship. I hope this clears up this matter.
