Advice and guidance will be in place all through the process as you can see above but there may be rules about how much advice you are entitled to.  You may have more than one advisor: for example, someone to explain your legal rights and sort out funding arrangements for you, someone to help you with the various stages of the procedure, someone from the specific discipline or course that you want to study, someone who can explain careers and job opportunities linked to the courses and so on. But there is usually one person who is your main point of contact and who will coordinate the process.
You might also get advice from the students union or other student organisations and from people who have been through the process themselves
Notes for HE professionals: This is a very important issue for applicants but it is especially important for newcomers. We know that in some institutions and some countries the role of the advisor and the amount of time an applicant is entitled to are very clearly defined.  In others it is much more flexible and negotiable.  Either way this should be transparent and you should think about adding a note here explaining that briefly, editing it to match your arrangements and adding a link to the full detail.
