How does that tax free income work then ? Please tell.
It works for a US citizen, and is regulated for that person under section 911of the US Internal Revenue code.
If I work in SaudiArabia or the UAE (just for two examples) the income I receive is free of any local tax, and...free of US income tax, with certain limitations.
The UK has similar procedures for their citizens, based overseas in a tax-free country.
Now, I do not know about the specific MD-11 contract mentioned, so...one would have to ask when applying.
