Fame
Look, you're probably not going to be picked for Dancing With the Stars, but there's a chance that your work will gain national attention. You and your crew might bust a huge shipment of drugs and catch one of the leaders of an international drug ring who's trying to sneak into America.
Yes, it sounds like a cheesy action movie, but that could be your reality. If you do have the chance to be a part of a big step forward in the fight for national security, you might end up seeing your name (in small print) in a national newspaper.
The chances of that happening are pretty slim, though. Your chances of fame are most likely going to come on a more local scale, when you help travelers get to their destinations or make the immigration process a little bit easier.
Immigrating to a new country is a long, hard, and often scary process. Helping people apply for their visas and navigate the immigration process can be pretty satisfying. You probably won't become famous for a big drug bust, but you could end up pretty popular with the immigrants and tourists whose lives have been made a little easier because of you.
