I feel America is a good country. I'm from India and I have been doing my masters here and it has been amazing. Everyone is so kind and considerate. My stutter has been pointed out in many of my job interviews in India even when I feel I rarely stuttered. I just went through one interview for part time on-campus work and I stuttered like crazy but I ultimately ended up getting the job. I'm hoping my full time job would have as good a culture of my part time workplace. But, if you still feel you want to explore other countries, I came across one comment in this sub about how Netherlands is a good country with respect to stuttering. Many prominent celebrities actually stutter publicly and it is a well known and recognised issue there, i.e., there is enough awareness. In other countries, when people mock stuttering, people laugh but it seems they are viewed in a weird manner here. More like how you would view a person who makes fun of blind people.
