Certainly the web pages from the USCCB I had posted earlier (and the ones which Elizabeth just posted)
seems to say similar to what Jimmy explains and what Elizabeth too and others argue…that it seems that in the US on the other Fridays one is not obliged but *urged *…and as noted above I can see the arguments from both sides…and have been on both sides of the argument …but if it is the case that that we are urged…so in the end I think penance and Friday being so important…we as Christians should follow the urging of our Bishops and do some form of Penance …except on solemnities (as Canon Law notes)…and maybe throw in Weds to boot like the early Christians!
As for your situation I would note this from Canon Law:
Can. 12 §1. Universal laws bind everywhere all those for whom they were issued.
§2. All who are actually present in a certain territory, however, are exempted from universal laws which are not in force in that territory.
§3. Laws established for a particular territory bind those for whom they were issued as well as those who have a domicile or quasi-domicile there and who at the same time are actually residing there, without prejudice to the prescript of ⇒ can. 13.

So in your case you can follow the Law of the Philippines. Which is that abstinence can be *substituted *by exercises of Piety such as reading the Bible, Mass, Rosary, acts of charity, teaching the Catechism…etc
(as per the Complementary norms to the Code promulgated by the Catholic Bishops Conference of the Philippines and published in the Canon Law Digest of the Philippine Catholic Church in 1987)…I found this info in the Code of Canon Law Annotated Published by Wilson & Lafleur Ltee
Now it is possible that something has changed since then…so you can check with the Chancery of your Diocese there.
(England too it notes also keeps the obligation of Friday Penance but allows for subsitution --but is very precise as to what may be substituted …to give a few examples of what they say one can substitute… abstaining from another food, alcohol or some form of amusement, going to Mass, visiting the blessed Sacrament, praying the Stations of the Cross, making a special effort to help somebody who is poor)
