It also reported that the visa application fee for Pakistanis has also been raised from $160 to $192. The US Embassy spokesperson said the decision came in response to Pakistan government’s modification of visa policy and fees.

Pakistan has reportedly already gone ahead for reducing visa period and fee increment for US citizens.

Meanwhile, the US is also looking into reports that Pakistan misused American F16s in the aerial dogfight with India recently, said reports on Wednesday. India has insisted that  Pakistan used US-made F-16 fighter jets in the raid, in a possible violation of the terms of use by the US.

While Pakistan rebutted India’s allegation, it hasn’t gone ahead to explain what military equipment was involved instead. On its part, India has given proof to the US about the use of F-16 fighters and AMRAAM beyond visual range air-to-air missile by Pakistan on February 27, sources said.

They said India was confident that Washington was carrying out a thorough investigation into use of the US-manufactured fighter as well as the missile onboard it in the offensive operation against India.

As part of the purchasing agreement, the US had put restrictions, the US had reportedly barred Pakistan from using the F-16s against any third country and it was only allowed to operate the fighter in self-defence and for anti-terror missions.

CNN quoted a US Department of State official as saying it was “aware of reports” that the use of F-16 jets may have been in violation of the terms of use agreement and is “looking into them.”

US State Department Deputy Secretary Robert Palladino said, “I can’t confirm anything, but as a matter of policy, we don’t publicly comment on the contents of bilateral agreements that we’ve in this regard involving US defense technologies, nor communications that we’ve with other countries about that.”
