I assume they avoid jobs involving standups. In roles where communication is fully asynchronous, a competent offshore dev whose written English is considerably closer to a native speaker than their spoken English might be able to hold onto the job for a while, especially if they're good at excuses. If they're applying for US onshore jobs with below-local-market pay, they might even be considered relatively productive members of the team.
