Is that pay you currently get "net" or "gross"?
Count the others costs of living you´re getting paid, too.
Unless you would want to live in the US, your current bottom line might be just as good after all...
But then, I don´t know where you work, if you or your family want to stay etc.?...(Are you bored of DXB after 10 yrs, kids older than 13...)
