There are several threads discussing your problem here. Biggest issue is that LPN programs are not recognized in the Philippines and so you cannot get a licence, what leads to the question of quality. The main reason why people are considering it anyway is money. But what I can get out from the info here, I have the feeling at the end you are better off getting the training in the US.
From my own experience with RN's who were relatively recently trained in the Philipines and then came to Canada, I would recommend the US as well. They have to catch up on many, many things, what takes a long time, so since you are a US citizen, I recommend training in the US at college that's widely accepted, so you won't have a problem should you choose to go for further training.
But look at the threads existing here, and verify the info. And the end it's your decision. Good Luck
