Maxwell landed in Barcelona on Friday afternoon ahead of taking a medical with the Blaugrana and then putting pen-to-paper on a contract to seal his move from Inter.
The Brazilian jetted in to the Ciutat Contal, via London, from Los Angeles after leaving the Italian club's pre-season training camp, and will be presented to the media.
Barca wrapped up the deal in midweek after failing to persuade Deportivo de La Coruna to part company with Filipe Luis, and are set to parade their first acquisition of the summer.
Having landed at 13:00 CET, Maxwell was taken to the club's offices where he posed for photos next to the club crest and then headed inside to prepare for a long day.
A medical split between the facilities in Camp Nou and the Hospital de Barcelona was expected to be straightforward and then the player headed back to the offices to sign his contract.
With little respite in between, Maxwell's presentation to the media was set to take place at 17:30 CET in the room above the club shop in the stadium forecourt.
Then it was on to the Mini Estadi in full kit to pose in his new colours as the Camp Nou was not a suitable back-drop because the pitch is being re-laid.
