Moving to the United States is relatively straightforward, but depending on your circumstances, it can take time, so patience is vital! For example, if an employer in the US sponsors you for an in-demand role, your visa application might get fast-tracked. However, there's a significant demand for entry to the US, so you could be waiting months or years.
Another option is applying for the Diversity Visa Program (also known as the Green Card Lottery). While the odds of winning are low, your chances are better if you arrive from a country with low immigration and have completed high school or have suitable work experience.
