KARACHI: Untied States has issued a friendly reminder to visa applicants from Pakistan. In a post on the US consulate karachis facebook page and shared by the embassy, visa applicants from Pakistan have been warned against fraud. A friendly reminder to our visa applicants; the US government does not offer visas to those who have not filed a proper visa application, the post read. If someone approaches you and tells you that you have been approved for a visa, or offers you a US visa in exchange for money, they are most likely committing fraud, it added.
