Boss Billy Davies and chief executive Mark Arthur will represent the Reds at a Football Association hearing as they attempt to secure a work permit. Findley, 25, agreed the move last month and has been training with Forest.
But to gain a work permit for him, Forest must convince the FA of his potential benefit to the club - both on and off the pitch.
A player will normally automatically qualify for a work permit if he has played in 75% of his country's international fixtures in the previous two years.
Findley, who faced England in this year's World Cup, has played in 11 of the last 12 USA matches but has only recently broken into the side and therefore has not passed the 75% standard.
The pacy forward was a free agent after leaving Real Salt Lake in the MLS and had been on trial with Premier League side Wolves.
