"I recently made my first posting at the AUS. My Spanish is God-awful. Has anyone ever come to the AUE with just the most basic of English knowledge, and eventually gone on to become fairly fluent thanks to the AUE's help?"
Not to my knowledge.
"Is it unrealistic of me to think the AUS will help my Spanish, after only five years of studying it, in a public high school?"
You've studied it for five years, and your Spanish is still God-awful, as you say?
"What about the AUI helping my Italian, after only studying it for two semesters in college?"
Don't put too much stock in that, espcially in view of your Spanish "success".
"In order to become bilingual or trilingual, fluently, is it necessary to take more professional training than this? Or is ... to improve after learning the basics? If this is the case, are the AU groups the best places to start?"
To become fluent in a language the best way is to become totally immersed in it. That is what I got for my German and English, in that order. My German fluency is gone, however, as I have not spoken the language in many decades. Now it is my native tongue that is suffering.
"How are foreigners treated here?"
Well, if they are courteous.
"And what have they been able to learn?"
Who's to say?
"Comments from anyone, foreign or native-English-speaking, are more than welcome."
I'm not a native-English speaker, but I'm the closest thing to it that you can get. I learned English at around the age of 16 some before, some after. I can do Standard Formal English better than many native speakers, but that's not unusual for one who has studied the language and not just grown up with it. On the other hand, I do "colloquial" too. ;-)
