Yes, and it would be a less strong argument. Being a recent immigrant in the United States is not easy, and feeling integrated into the new country is a challenge. Being a recent immigrant to China is incredibly hard, and feeling integrated is impossible. All arguments could be made on all sides of every issue; that doesn't say much about practical realities.
Only true if you're willing to be ignorant about how poor integration is in most of the Asian countries compared to the US.
> you'll always be a foreigner there
This isn't true in the US, if you learn the language.
language != culture
No, but communication plays a huge deal in being able to absorb the culture, as well as share your own.
Very true. Most places in the US are fairly welcoming if you can speak English and communicate. It's even common for xenophobes to cut out an exception for immigrants and minorities they know personally and feel friendly toward.
Also the american culture is very wide spread through media. Watching Hollywood, music, sitcoms, talk shows, stand ups etc. ever since I was 10 yo and able to understand english definitely helps absorbing the culture even from eastern Europe as myself. Visited the US for 2 weeks and really felt as if I was no stranger at all.
we don't care where you're from. I'm not running a little 'who's a citizen tally' in my head.
Minorities are not treated like foreigners or alien.
