I think if you are planning to acquire properties or land in the Philippines in the future, a natural born Filipino who acquired a foreign citizenship will have limitations.

Here's some info about it.

Also, I think if you have kids that weren't born in the Philippines and you own land/properties in the Philippines as well, they can't inherit it unless they have dual citizenship. Anyway, here's an article about it. http://www.balita.ca/2012/01/30/rest...ution-of-land/
