Are exit (especially) and re-rentry dates given when applying for re-entry permits on O visa strict?
That is, if something went wrong with travel plans, would you be expected to apply for new permit?
Doubt so, but just double-checking...
TLDR : Answer Summary
The dates provided for exit and re-entry on the application for re-entry permits on an O visa are not strictly enforced. If your travel plans change, you do not need to apply for a new permit based on the dates you initially provided, as they are not set in stone and are not essential for the permit's validity.
