I am in a very similar situation, so I know exactly what you are going through. My parents brought my sister and I to the U.S when I was 14. I entered high school not speaking any English and by senior year I was enrolled in A.P English. I graduated top 5% of my class of almost 700 students and was accept to 8 different universities. My parents put all their efforts into paying my college tuition with money from cleaning houses and doing construction work (in my home country my mom was a dentist and my father was a veterinarian). They have always paid taxes and have never even received a speeding ticket.
However, it got to a point were they were not able to keep paying for my tuition and I had to stop going to school in my senior year. My little sister is also graduating high school with an outstanding G.P.A and she will not be able to attend college because, like myself, she does not qualify for any financial aid/scholarship/loan.
It is so sad to see other people in my situation and even sadder to read these ignorant and negative comments. On the other hand, I am so happy to know that there are supportive people out there that understand and support our cause- I believe that together we can make this dream a reality,and this country a better place.
