Pakistan has an e-visa system. This means that you do not have to go to the embassy to apply for your visa. You can arrange everything via their official website.   For the visa request we will send you the Letter of Invitation (LOI), which you can upload online during the process. After approval of the visa (this can take a few days to several weeks) you will receive a Visa Grant Notice in your email. This is actually your visa and you must print it and bring it with you during your trip. When you arrive, you hand this over at the customs.
