My current status is F1/ OPT (OPT began: Jan 06 2019, ends Jan 06 2020), how long can I be outside of the US for?.

The purpose of OPT is for an individual to receive training in the US. The total time that an individual can be without work during OPT is 90 days, and during a STEM extension, 150 days. Persons who take extended trips out of the US could face extended questioning by CBP when reentering the country. An individual on OPT must have a valid EAD to return, so leaving the US during the extension application period would cause problems.
