Is a foreign company required to obtain any other permission from any other organization for opening and maintaining of its branch/ liaison office in Pakistan?

A foreign company is required to obtain a permission letter from the Board of Investment, with a specific validity period for opening and maintaining of its branch/liaison office in Pakistan. A copy of such a permission letter is required to be furnished with the documents meant for registration. Renewal/ extension of the permission to open/maintain a branch/liaison office is also required and can be obtained from the Board of Investment on the expiry of the validity period of the permission originally granted. Whenever such renewal/extension is granted, a copy must be furnished to the registrar concerned.
