The reason is very simple; your best chance of getting an immigration visa to places like the USA, UK, Australia, or Canada is going to be on your first attempt. If you have a problem, any problem that gets the visa deigned, then every other time that you apply for any visa they are going to go through your application quite rigorously. It is worth it to get the best immigration lawyer that you can the first time to give yourself the best chance of fulfilling your dream of immigrating.
