Americans of Pakistani origin braved sweltering heat on Saturday to welcome the premier to Washington DC.
In Washington, where Khan arrived at the weekend, the Pakistani premier can be expected to highlight Islamabad's support for U.S. talks with the Taliban, and point to the arrest of Hafiz Saeed, the founder of the terrorist group behind the 2008 attacks in Mumbai, as evidence of good faith in the struggle with extremism as he seeks relief from the relentless economic pressure from Washington.
On Monday, the prime minister will arrive at the White House and after the book signing ceremony, he will attend two sessions: a small group meeting and an extended meeting.
Trump and Khan, who once exchanged angry Tweets over Pakistan's half-hearted efforts at combatting terrorism, will meet over lunch accompanied by their respective delegations and the tone of the meeting is expected to be urgent and business-like, with the focus on the Afghanistan peace process.
"The US has stopped military aid to Pakistan so they would want a restoration of that, and then of course they would want the pressure of the Financial Action Task Force to ease off - that's very significant because if that doesn't ease off then their whole economic situation is imperilled".
Meanwhile, hours before Khan's arrival, Pakistan hired the services of lobbying firm Holland & Knight.
Hundreds of members of the community belonging to Washington metro area and other states came to the USA capital and lined up along Massachusetts Avenue near Pakistan House, where the prime minister is staying during the visit.
Blank editorial spaces have been appearing in Pakistani newspapers ahead of Khan's visit as articles critical of his military-backed regime have been culled even as the pro-government media is drumming up enthusiasm for a visit that the Trump administration is terse and business-minded about.
Reynolds will lead a team comprising other former members of Congress, former senior Administration officials, Capitol Hill veterans and other professional experts to lobby in the U.S. on behalf of the Government of Pakistan.
Former Pakistan Ambassador to the UN Munir Akram and renowned businessman Shahal Khan also called on the prime minister in Washington on Sunday. The Embassy had no lobbyist during the past six years.
A bipartisan group of 10 influential American lawmakers asked President Trump to raise the issue of human rights abuses in Pakistan's Sindh province in his meeting with Khan. "Pakistani-Americans are here to show their love for him", Johny Bashir, a Virginia-based PTI enthusiast said, as people waved the Pakistani and American flags to express their support for the visit.
The US has also put Pakistan on a watch list for failing to protect religious minorities.
