Hello kabayan. Just giving my 2 cents worth here. Maybe more would like to give advise but you left out some info: i.e, have family/kids, is the offer more than what you're receiving now?

Here are some facts: Your salary's worth would highly depend on your lifestyle. Though you still can enjoy your life by living simply, which a lot of wise kababayan's are doing, may they be working in the oil industry or any high paying job. Bring a lot of books. Nothing beats the pleasure in reading!

Housing prices these days are going down, and you may want a shared room in a decent place(please check QL classifieds).

Hereabouts, and sorry to say, where you graduated back home doesn't count for much. It's your real time skills that will spell the difference or you can kiss butt to go up. Not to douse your expectations, over here you'll be used beyond your skills but not fairly compensated.
My suggestion: negotiate now for more salary, or look for a much better company. Don't be in a hurry. Don't miss this chance. Why aim the moon when you can reach the star?

Answer this truthfully: are you willing to sacrifice for that amount? Remember, NOBODY is immune from the attendant problems (goes with the territory) we(ofw) all experience.

But if you really feel for this job then go for it and may God bless you. You're most welcome to join the diaspora! :)
