Ralf Rangnick has been granted the work permit which will enable him to begin his reign as Manchester United interim manager.
The 63-year-old German will be introduced in a news conference on Friday and will take charge for the first time in the home match against Crystal Palace at Old Trafford on Sunday.
"As all paperwork has now been completed, we will hold an in-person press conference with Ralf Rangnick at Old Trafford at 9am tomorrow morning," United said in a statement on Thursday.
United announced the appointment of Rangnick as Ole Gunnar Solskjaer's short-term replacement on Monday.
But Rangnick, who was manager of sports and development at Russian club Lokomotiv Moscow, had to wait for a work permit before he could begin his role at Old Trafford.
He will have a watching brief on Thursday night at United's Premier League home game with Arsenal.
Caretaker manager Michael Carrick takes charge for a third time against the Gunners, with the former United midfielder having overseen a Champions League win at Villarreal and a Premier League draw at Chelsea.
Rangnick will remain as manager until the end of the season before starting a two-year consultancy role at United.
