USA Patriot Act (group one)

The USA Patriot Act has been a real headache for us international students. It might be fine with students from developed countries and areas, but definitely had a negative effect on students from the developing countries like my country. I still remember the year when a lot of good students were refused to enter the US after the 911 affair. It's understandable that a country should do so to fight with the terrorists, but is this the ultimate method? Actually, I think in other countries this kind of act probably will not draw so much attention and debates, but in this country, freedom is no fundamental that people have to think about what it really means.
