Hebrew courses in Israel
There are a few schools and institutions in Israel which offer different Hebrew courses to international students and/or visitors. Among those institutions: Ulpan Kibbutzim that takes place in no less than 8 different kibbutzim in Israel, The Hebrew University, Levinsky College and more. Most schools offer you the chance to get a student visa so there's no problem with this.
Each one of those institutions offers a different program which takes around 4-5 weeks (at least - can also be longer if you wish) so I've attached a link at the end of my message to an article about the different programs you can choose from and i advise you to contact those that are relevant to you directly to get all the information you need about the admission, fees and any other information you may need.
