first make sure you can get a job. apply until you do, and then apply for a visa and then if you are approved confirm the job offer and get an apartment, a little harder than it sounds. lots of paperwork
hey i dont really know about the visas but you need to be financially secure, and i think the maximum you can stay here is 6 months without working?
if you get a good job or marry it will be much easier,
sorry if this doesnt help aha just trying to be helpful!
