Scholes added after seeing applications blocked in November and May: "Juan Agudelo is a 21-year-old US international.
"The US are 13th in the FIFA world rankings, England are 11th. Can you imagine an England player at 21 with 18 caps for his country who gets turned down for a work permit anywhere? It’s completely wrong.
"Of course we are caught up in the whole environment with (FA chairman) Greg Dyke’s commission, even though the rules are clear and that shouldn’t be a factor.
"But there has been without doubt a hardening of stance. A player who should have got in because he would have contributed to the game has been turned down."
