JP,
If you have a decent job in the Philippines, don't come here and allow other nationalities to exploit you.
The offered salary is too low, for the sacrifice of living here and away from your loved ones.
Here, people are often cheated and they don't get what they are told, including scope of work!
Please consider carefully before you regret the move!
I suggest you talk to someone from your country that is already living here, to have a better insight of what you will be exposed to!
