Boucher is expected to meet with Pakistani Foreign Minister Shah Mehmood Qureshi and other officials during his stay, local Geo TV channel said.
The war on terror, Pakistan-India tensions and other issues will come under discussion.
Boucher is likely to visit New Delhi for talks on ongoing investigation into the Mumbai attacks, reports said.
