Reputable distance learning journalism courses allow you to learn at your own speed and study from home.
For students from abroad, the London School of Journalism offers the widest range of practical writing courses, including options suited for those wishing to work as staff or freelance writers anywhere in the world - see lsj.org
The NCTJ also offers distance-learning options, although the nature of this course, which is primarily geared towards careers in the regional press in the UK, means that attendance courses are preferable for most candidates.
The two distance learning journalism courses run by journalism4schools are primarily designed for those still at or about to leave school in England and Wales and aim to provide the cheapest way of acquiring core skills and getting some initial feedback on your writing now. See Starting Out In Journalism or Media Law for Beginners in the menu.
