Do you plan to travel the world, or do you have to visit another country because of some emergency situations? Traveling to a different country is not like a road trip which one can plan anytime and set off immediately. It takes time for the preparation of all the necessary things. One must get a visa which is an important document that gives your permission to enter a different country.
If one is in an emergency, getting a visa may delay their schedules. This can be solved by applying for online visas which take lesser time and are more convenient.
