My Audience and purpose

I believe that as of right now my main audience would be those who make and approve the immigration laws and set up the process and on a smaller scale those who have to go through the process of becoming a citizen. As for my purpose, I'm not sure exactly how long and how much it costs to go through this process, so if I thought it was was reasonable, I would say my purpose is to focus on why this process is essential for immigrants to go through. But if I find the process isn't reasonable and could be better, then I would say my purpose would be to convince those who make the process shorter, easier, and more appealing to immigrants.
