Pakistan prospect Khan banned from UAE cricket for five years
Khan, who has been living and playing in the United Arab Emirates with the intention of representing the Gulf country, was called up to the Pakistan camp after blazing back-to-back centuries last month in the Pakistan Super League.
The 28-year-old was "found to have breached his obligations owed to Emirates Cricket Board", said a statement from the UAE governing body.
"After a detailed investigation, Usman was found to have misrepresented to ECB about his decision to play for the UAE team and has used the opportunities and development provided by the ECB to him to seek out other prospects."
The decision rules Khan, who was reportedly 14 months from satisfying the residency requirement to play for the UAE, out of the ILT20 and Abu Dhabi T10, both played in the country.
He will now target Pakistan's T20 series against New Zealand and a ticket to the T20 World Cup in June, which will be held in the United States and the West Indies.
