Moving to another country may be for a wide range of reasons. General ones include changing jobs, changing lifestyles, improving work prospects, new careers, studying abroad, and several other factors. There are, however, laws in place for each country in which foreign national attempts to enter it, and the individual must abide by those laws and satisfy all the conditions. For example, in 2016, it was reported that 28.5 percent of current residents of Australia either emigrated or were born in another country. It is also important to have a clear understanding of the laws of the host countries and, if important, to consider the services of a legal aid worker.
