You not give enough detail. The nationality of your girl, can be a determinate factor. Philippine stay here with bf, or to work, and do all tricks to stay as long as possible.
You not mention age. From 50 years old, retirement is best. Even if your wife is not 50, she can get a following spouse visa. If your wife want a job as teacher, then as said go for that. Indeed avoid ED visa. Gives problems often if you travel back into the country.
Some Philippine women, could fo that, but not a girl with the right mentality. My wife, 30 years younger, far from a child at now 34, never been in that. We have a very normal life, living in Thailand, as a real couple.
Mine is 30 years younger. I not brought her home, but out of her country, Philippines. We live in Thailand. We knew each other 6 years, before making that decision. It is not about age, but mentality.
