Security personnel of New York's John F Kennedy International airport searched Pakistan's Prime Minister Shahid Khaqan Abbasi recently.
The people of Pakistan have expressed anger in social media describing the incident as an embarrassment.
In a video footages, Shahid Khaqan Abbasi is seen picking up his bag and coat and walking out of security check at an airport like any ordinary passenger.
The visuals have been termed as a "major embarrassment" for the country by much of Pakistani media.
Geo News has said the Pakistan prime minister was in the US last week on a private visit, reportedly to visit his sister, and followed standard security protocol for all passengers.
Abbasi is known for his simplicity, said NDTV quoting Geo News.
In the same visit, he reportedly met Vice President Mike Pence. The US has told Pakistan that the country needs to do more to tackle terrorism from its soil.
Some media reports criticised Abbasi for going through what they call a humiliating process for the head of a nation despite a diplomatic passport.
The incident comes at a time the US is considering tough measures on Pakistan, including visa bans and other sanctions on individuals in the Pakistani government.
The US has imposed sanctions on seven Pakistani companies over alleged links to the nuclear trade.
The ties between the two countries have been frayed in recent years over Pakistan's suspected support for militants waging war in Afghanistan, something Pakistani officials deny.
The Trump administration is believed to be considering unprecedented political penalties on Islamabad for harbouring Afghan militants waging war on the US-backed government in Afghanistan.
US officials say despite a suspension of $1.3 billion in military aid in January, Pakistan has failed to take decisive action to crack down on Afghan militants on its territory.
