What is the basic information one needs to know before applying for a visa?
One has to be clear on which category one needs to apply for when it comes to visa applications in any country. In addition, one needs to know how much duration they plan to stay and how will they support themselves during that stay. These are the basic questions to be put in place. Henceforth, the process becomes easier.
Is the process of visa application time-consuming?
If one submits documents without any complications and authentic documents the process takes less time. If there is any name or address mismatch the process takes time. To rectify it, some additional documents might be needed as well. All this depends on which country and category you wish to apply for.
My application was declined due to poor advice. Can I reapply quickly? If not, when can I do it next?
It depends on at what stage your application was declined. If no misrepresentation exists, then the new visa can be applied and the process can be done quickly.
