Is there a trap to work in Gabon?

I have seen many people working abroad with high salaries, but actually they have to pay a lot of management fees, meals and accommodation, which are not told in advance, so many people come back and find that they don't earn as much as they thought.

In this way, when you go abroad, you'd better find a reliable foreign trade company, not such a commercial company that doesn't know the ins and outs.
