You can move to America but it is not a simple process – for instance – you can only live there if you:
Apply for a work permit
Have a Work /company sponsorship
Marry a US citizen
Are very rich
Even then – if you require permanent residence there you will still need to go through the immigration process.
The easiest way of living is the USA – is to apply for a ‘Green Card’ You can do this by participating in the US GREEN CARD LOTTERY. The program grants 50,000 visas to people world wide every year, authorizing them to reside and work in the USA!
