>>793450>is it obvious that you're an ESLit depends on your command of the language; in text, if you're shit at it, then obviously yes. if you're actually grammatically competent, to at least an 8th grade level (according to some statistics, a large portion of adult americans are illiterate below a certain grade level), then no.
that shit is much more obvious during speech, though. you can't hide an accent, it will come out sooner or later, and you'd have to put in a lot of effort to mask or permanently lose your accent.
