If you are in California, talk to the Pinays who are oldtimers there. More likely they will tell you they wanted to go home but they are worried of their financial security in the Philippines. I have a lot of college classmates who settled in America and they say that if given a choice, they want to stay in the Philippines. I'd still say it depends on your values. There are people who easily adapt to the culture of a foreign country and there are those who try hard to cling to their original culture.

As for the expats going back to live a life in your homeland, ask yourself why you want to go home. If it's about the family then go home.
