Hi friend,
living in the Us, UK, Australia, etc can be viewed from two perspective. One is leaving ones country and trying to procure a visa to any of these countries. The processes involved is one part. The second aspect of it is deciding to remain in the US, Uk, etc. The approach to each of them is different. However, if remaining in the US, UK, etc is the subject matter, then there are so many things to be considered such as culture, the part of the country to live in, the cost, etc. Whichever way you want it written, you can surely count on me. Thanks
