The Daily Mail says Conte stayed the night at the club's plush training lodgings on Monday ahead of Tuesday's noon announcement.
The Italian - and up to six of his coaching staff - intended to take Tuesday's afternoon's training session but were unable due to employment red-tape, which will also preclude him from conducting Wednesday's press briefing ahead of Thursday night's European Conference League game versus Vitesse.
He did, though, address his new colleagues and players in separate afternoon meetings on Tuesday.
Conte also watched his new players train for the first time at Spurs' Enfield HQ and was also due to spend a second night at the training ground.
If, as expected, his work permit arrives on Wednesday - then Conte is expected to be in the dugout for Thursday's match.
