Pam ...
I can understand your position, but here's another point of view.
My family sponsored an RN from India that Dad had met when he was head of a large corporation in India and he was hospitalized for appendicitis.
When S arrived in the US, she understood and spoke English quite well, but we couldn't understand her. She spoke with an British-Indian accent that made it almost impossible for our American ears to understand what she was saying. My brother sat her down in front of the telly with earphones so that she could learn to speak English with more of an American accent. (btw ... it was the first television she had seen in her life.)
She was one of the brightest people I had ever met. She ended up being the head of Standford University's cardiac intensive care unit. Had our family not taken the time and care to help her learn to speak English with an American accent, she may have never had that opportunity and her patients would have missed out on having an excellent nurse available for their care.
My current doc is the most competent doctor in town. He often has the bedside manner of an angry grizzly bear with a roar to match.
Looking back, I am glad I decided to choose competence over a nice bedside manner as my priority. Under that roar is a kind and caring competent doctor who is seriously overworked in this small mountain community. A man I admire greatly.
Edited because I was repeating myself .... oops
