I’d like to know if it’s okay to visit Korea or Canada once a travel authorization comes through during my employment-based case.
After PERM labor certification is approved, I-140 is approved, and travel authorization comes through — is it okay to visit Korea or Canada?
If you’ve maintained lawful status, you can obtain a visa matching your current status and enter. However, if your status has been maintained for a very long time and you’re concerned there could be a status issue, it would be better not to leave.
