Immigration

I feel that immigration is a real problem these days in the United Staes because so many people want to come here to have freedoms and to have a better life. I think that we have to find a way to allow immigrants who have been living here for long time to get get citizenship easier because I hear that it is nearly impossible these days. Also, I don't really know much about the illegal immigrant problem and I was wondering if anyone did by chance. I mean yeah people are coming into our country but if they are coming here with good cause just to find a job and help to put food on their family's table then what's the problem?
