That depends individually. I can speak Russian accent both with Russian and English that nobody ever would recognise. Normally I have American accent, but I’m having ‘you think this is bad neighbourhood’ kinds of hires with friends very well made Russian accent.
I know many people like that either. I personally spent some time in Moscow, nobody ever knew I’m not a local. Same goes for a friend, we both were laughing at them being unable to recognise we’re not locals.
I believe this might be truer for small distant regions, where people might have their own local accent there. Plus not too many people to blend in that easily. But in general, even if one speaks differently, it might not take too long to adapt to speak like everyone else.
