Qatar Airways today confirmed recent comments made by Chief Executive Akbar al-Baker about the proposal. Al-Baker is overseeing development of a new airport in Qatar's capital Doha slated to open this year.
The US Embassy in Qatar had no comment. US Customs and Border officials could not immediately be reached for comment.
The US in January opened a preclearance post in the nearby United Arab Emirates capital of Abu Dhabi that lets passengers avoid immigration and customs lines on arrival. US pilots and members of Congress have criticised the facility, alleging it could benefit UAE national carrier Etihad Airways over US airlines.
