There are so many ways in which you could make money advising people. I mean most people prefer to get some help from someone rather than doing on their own. Some people search online for help just like all of you who is reading this article or may simply seek to ask friends or family for advice on certain matters. Very few would be inclined to ask for professional help in the beginning but at some point they realize the benefits that can be gained from doing so and pursue that avenue. So eventually all of them end up paying you money for your advice.
Now when it comes to immigration you could become qualified to become like all of the family migration specialists out there and earn some good money. The path to becoming one is a bit of a long path that you need to prepare from the very beginning. You need to have a basic degree at least to proceed on this path preferably something along the lines of business, foreign language or communications. To get to the best position in the field of course getting a law degree would be ideal. Otherwise you could be left stuck being merely a consultant who does not let you earn as much money as it would have allowed you to earn as a lawyer. I say this as you learn a lot of about the laws that apply in this situation and will be more helpful to the clients that come seeking your services, which basically means that you would be able to charge more.
Most successful family migration specialists are also proficient in at least a couple of foreign languages. So it would be ideal if you could possibly follow some course that could be helpful for you. On the same note of following courses you could also possibly follow some law courses if you were unable to get a formal legal education to better improve your services and your understanding on the subject area. Of course even if you are not a qualified lawyer you should get your notary license so that it allows you to be able to legally approve certain documentation that you clients would need to use for their application, also check this out for investment immigration.
Otherwise you would have to find a lawyer who would do that for you which means another expense for you. This whole service depends on experience so working under someone could be helpful to understand how best to handle a situation of this nature. That is up to you of course. But just saying people prefer more experienced people.
