И тут возникла проблема: надо ехать домой в декабре, а лоеры говорят лучше во время процесса продления не ездить, цитирую:
Несколько месяцев терять не хочется, поэтому склоняюсь заплатить премиум, но реально нигде не смог найти, что действительно могут быть проблемы?It's very difficult to travel while an extension of H-1B/H-4 status is pending. It can cause conflicts between the I-94 that you had at the time of filing (which is the one that gets extended) and a new I-94 that you would receive after returning from the U.S. In some cases, travel during a pending extension case can cause the extension to be cancelled and then it has to be re-done, which doubles the time and cost of the entire process.
We recommend that you either ensure that the case is approved before you go (i.e. use premium processing, a government service that costs an extra $1,225) or hold the filing and only send it after you've returned.
