Being a former OFW for 8 years, heto lang masasabi ko.

1. Kung hindi ninyo kaya mawalay sa pamilya nyo, then don't go work abroad.

2. Don't be a tourist, remember that you went there to "earn" money not to splurge on electronics, nike/doc martens and jewelries. I've seen them all, believe me.

3. Kung hindi kayo marunong makibagay sa ibang tao/lahi/kultura, then forget it, don't even think about working abroad.

my 2 cents.
