Usually, to be able to enter the destination country, you will need a visa. Like, UK, you need a visa to get there, even to stay there. You must visit to get the visa you need. However, make sure that all things related to the visa you have prepared properly, so there are no mistakes.

An error on the visa will make the visa refused in your destination country.
Sometimes, most people who have been denied a visa or have had a visa problem will hide the problem of visa rejection or cancellation in the past. In fact, information related to visa refusal has been previously documented. So that if the applicant intentionally hides the matter, it will be considered fraud and of course the visa will not be processed.

So, if you have ever experienced visa denial in some countries, be honest and tell the truth so that you are not considered a fraud and the business you will face will be longer.
