It is, for what it's worth, one of the most common reasons I hear from Chinese friends of mine who move back to China after living in the USA. They like a lot of things about the USA but expressing their full intellectual range is a constant and often unsuccessful struggle even for the ones who speak English fairly well, and they feel like they're not able to live up to their potential as a result. Having lived in China a bit to immerse myself for language learning, I can totally get that. It is very humbling to hear something in a conversation, have complex thoughts about it, and be completely unable to respond with any nuance or subtlety or precision.
