All-rounder Fawad Alam is being investigated by the UK Border Agency following his appearances for Woodhall Spa this season.
Fawad is being probed for allegedly breaching the terms of his visa by playing for Spa in the Lincolnshire ECB Premier League.
It is believed the matter came to light during Alam’s appearances for his country during the recent one-day series with England.
Alam joined up with Pakistan after his stint at Woodhall, where he averaged 76 with the bat and took 25 wickets in seven matches.
But his right to play club cricket in this country is being questioned by the Agency, which is responsible for securing the border and controlling migration in the UK.
“We can confirm that we are looking into these allegations,” said Agency assistant director Phil Dyer.
“Clubs that wish to employ sportsmen or women from overseas must check that they comply with the conditions attached to their visa.”
Woodhall chairman Tony Armstrong said he had no knowledge of the investigation into Alam.
