At a guess he had a 90 day stamp from a Non O?
Has not done an extension.
So this was to be his first?
To even consider trying to obtain a 12 month extension the 800k must have been in bank for two mo tha to meet compliance.
Your post is tad confusing. What do you mean.,.. What actually expired.
The Non O or the 90 day stamp.Check passport to see date of current permission of stay.
Given only one page remaining in pp then not good situation.
