I’m 61 years old a guy live in Northern California with family .I just remember about illegal stay Japanese a guy. he was maybe same years old about you. he came from NYC . he had some part time job then get cash always . He lived room share house. We worried about him because he didn’t have social security , no ID and no health insurance . Years later suddenly he faded out from us. If you have green card, social security and health insurance nobody worry but if you doesn’t have all please consider about your future . After November presidential election if trump win I expect international students, foreigners and illegal aliens their living will hard. you take care and make happy.
