Can I submit my paper somewhere else during rebuttal period? During a rebuttal period, with reviews that show a strong indication of overall reject, can I submit the paper to another venue (without violating concurrent submission rules)? The submission deadline in the other venue is before the final response of the current venue.
If you want to submit elsewhere, the proper course is to formally withdraw your paper. Send a note to the editor. Then you are free to submit elsewhere. Don't make assumptions.
