In general, one-time travel to present at a conference would not require disclosure to sponsors.  If, however, that travel establishes a relationship with a foreign university, government, or other entity (e.g., results in an honorary or visiting appointment or an offer to set up laboratory space at that institution), then that may need to be disclosed, depending on the sponsor and their specific guidelines.

Conference travel must be registered in the Travel Registry and will be reviewed by International Support Services to evaluate security and compliance risks.
