It can be a nail-biting experience, knowing that you have a trip coming up and your passport is...somewhere else. If you're lucky, you're going to a country that offers an eVisa and your passport never has to leave your hands. In that case, you should only need 3-5 days to get your travel visa via email; print your documents and bring them with your passport when you arrive in-country. While most travel visa services offer expedited processing options, many embassies and consulates do not. If time is of the essence, it's a good idea to reach out to a travel visa service right away; they can give you their best estimate as to how long it'll take and the fastest possible way to get your paperwork in order.
