Question about UC verification

My son received a request that he verify an activity that he listed on the UC application. He sent the verification document via email to UC on Jan. 8. Will he receive confirmation that his verification was received, or some other confirmation that the verification was sufficient? Should he contact the verification office to confirm that they received the document?

Just for piece of mind, I would give it a couple of weeks before contacting admissions. Was there a deadline for the submission?

Deadline is January 31.

If the deadline is Jan 31, it may take a while for them to send a confirmation so if you have not heard by the 22nd, then I would send email to inquire.

Thank you!
