Seth and Paul have given some great advice here . 

Take it from someone who has no university degree and wishes he did have . You will have an advantage greatly over not having one . Job prospects can be tough even with a degree so im sure you can imagine how it is infinitely harder without such qualifications. 

You may hate it now but it will be worth it in the long run buddy . Good luck with your studies.

Mohammad I agree with you in part.

I don't agree that a college degree is a waste of time. The skills of research, analysis, written presentation and debate are useful tools in real life.

As you know, there are a vast number of professions, where a college degree is required. 

I think you are over generalising on employers shifting their mindset.  There is a huge debate about employers being unhappy with the skill sets of graduates and an argument that gaining skills by work is the way forward.  But, the non-graduate may face an invisible wall when they want to climb the career ladder.

There are famous examples of drop outs who have made it, but as Learner SC has said, how many didnt make it?

I don't want to see intelligent, bilingual Chris, working illegally, in a low skilled, badly paid job and paying high rents in England, because he hadn't done his research from the advice given.

Chris, what do your close friends and relatives think?

I think what a college degree/diploma gives you is a wider range of options. However, it doesn't mean things would automatically happen, doors will not magically open. 

However, some doors will never open if you drop out now.

There are sucess stories of people who drop out and make it good. However, how many drop out and don't make it?

 I would say try to finish what you are doing now. Moving to another country to work sounds easy but as the others said, in reality probably not so.

As you are not a citizen of an EU member state (at least, that is the conclusion that I have drawn from your profile) I believe you will find it quite difficult to find work in the UK.
Immigration is a hot topic at the moment in this country. The government knows it is powerless to stop people immigrating here from EU countries because of the freedom of movement rules. It has therefore taken steps over the last few years that have made it much more difficult for non-EU citizens to migrate here, in an attempt to make it look like they know what they are doing and that they have the situation under control. To get a work visa you must first have a job offer.  If you do not work in a profession where there is currently a shortage of workers (like nursing for example,) you are also less likely to get an offer. Additionally, many employers specify that they do not accept applications from non-EU citizens simply because it is too much hassle. As for internships, there are probably schemes out there for people like you but you'd have to do a bit of research to find out more about them. That's probably not the news you were hoping to hear. Seth's suggestion was good, there will be companies in Japan who have links with companies in the UK and that could be a way in for you to work in this country.

Please don't drop out. If you need to take a break, take it.

Finish your college degree. It will be worth it.

You will then have more opportunities available to you.  

See if you can join a company that may send you to Australia, Canada or England and thus use your language skills.

Think carefully about what you are planning to do.
