With a visa application, the first thing you need to understand is that receiving such a visa is not a right, but a privilege. The country can always deny you the chance to enter their territory if they wish to do so. Even if you already had the opportunity to enter the country before as a tourist, you could still end up getting rejected this time. Whether you are applying as a tourist or as a worker, the opportunity to approve your visa lies in the hands of the state.
Each country requires documents before giving the visa. If you fail to submit all the requirements, your application might get denied. However, even when you succeeded in presenting all the documents, you could still get rejected if the country wishes to do so.
The documents you give will undergo a thorough check. The officers will determine if they are valid and legitimate. They will also check if you have a criminal history. If you are applying to work in another country, there are also rules on the distribution of visas per country. Therefore, even if you submitted valid documents, but the field where you wish to apply for a job already has a significant number of workers from your country, you could get denied.
Can you sue the government?
If you feel like you already submitted all the required documents and you did not violate anything, you might want to sue the government for their action. Before you do so, you need to go back to the idea that the sole decision to approve or reject your visa application is the right of the state. They have grounds for visa rejection, but they do not need to indicate such grounds on each specific case. You cannot sue the government if they did not grant your request, and such an effort will be futile.
You can appeal
If you believe you have a robust case, you can appeal your application. You have the right to appeal your case provided that you have reasons for doing it. The government will then assess the appeal within a brief period and tell you if they have reversed the original decision. However, the chances of reversal are minimal. Unless there is something new that came up which could make the state change its mind, your appeal will most likely fail.
Wait for a while
If you desire to work in the UK, you might have to wait for a while before submitting your application for a work visa. You could get approved the next time if you provide the required documents and if circumstances have changed. In the meantime, you need to start going through the previous application and determine what went wrong.
You might also seek help from legal experts this time. You can check out www.gulbenkian.co.uk for further information. Perhaps, you did not receive your visa the last time because you did not have the correct information regarding visa application. This time, things could be more optimistic for you.
