While in some countries the visa process lasts just 5 minutes, is free and involves filling out a simple electronic form, in other countries the process is a bit more uncomfortable since you have to fill in longer forms, pay fees and provide supporting documentation that must be presented at the consulate on duty or at the visa management center (or by courier).
The visas originate a problem for the country that imposes it: it hinders the arrival of tourists and, therefore, the economic development of the country.
Although the specific requirements vary, most countries require the submission of recent photographs, fill out an application form and present the current passport. The passport is necessary because the visa is attached to a blank page of your passport. Other documents can also be requested, such as a detailed itinerary of the trip and letters of invitation. The frequent changes in the requirements and regulations to obtain visas make the search when organizing a travel itinerary a confusing and laborious process.
In most countries, the visa is stamped on or attached to a blank page of the passport, although there are some exceptions.
