Moving somewhere and not knowing the language is extremely common. My mother has been in the USA for 40 years and speaks very little English. She focuses on Spanish speaking neighborhoods and businesses.
Many of her friends have also been here decades and speak zero English too.
I absolutely agree. I didn't make my point of learning the native language. I'm annoyed by native Spanish speaking immigrants purposefully not learning English while living in the USA for decades.
It seems it also happens with Americans that migrate to other countries.
