For certain people, yes. But i can say professional attitude and study culture will help more than this. Some of my colleagues who don't help SAP certification but have those culture can get offering more than 500USD daily, it means more than 10K USD per month. This also still happens in D-category group such as Indonesia for company to company contract. In middle east such as Qatar or Dubai, this amount sometimes is nett and always free from tax. While in USA, i heard it depends on country and the tax could reach around 30%, this is why one of my friend still choose Singapore for monthly 7500SGD rather than going to USA for annual 100K USD.
In other side, i still cant find my colleagues with certification getting such offering.
to be contd.
