Which country has the most job opportunities for foreigners?

there is no such country in this world (especially during these difficult times)... it all depends on WHO you are, WHAT skills you possess, HOW you view successful employment etc.

you could go to a country with abundant employment and NOT find a single job, while going to a place where its so difficult to find work, and subsequently find employment. it all has to do with YOU and your outlook on life. thinking that going to a country with healthy employment history would make you easily get a job there, will have you fail in life time and time again.

have a valuable skill in hand, speak the local language, be positive (emotionally/physically), and most importantly HAVE THE PROPER WORKING VISA ...and you will be fine anywhere!

Nigeria . is just that is not well paying jobs

It's arguably far easier to hustle in Nigeria than many places because there's less in your way if you want to get something started.
