If you come to the UK with permission as a visitor, you cannot apply to switch to a student category in the UK, you will need to return home to apply for permission to study.
Tier 1 (including Post Study Work)
You can study while in the UK under any of the Tier 1 working categories.
You can work and study while in the UK with Tier 1 Post Study Work. The rules do not state how much you can work or how many hours you can study -however, you should have a visa that reflects your main purpose to be in the UK. If you travel in and out of the UK, you will have to explain your reason for re-entering the UK. If you are working and studying at the same time, you need to show that working is your main purpose.
If you intend to stop working, it is advisable to switch to a Tier 4 (General) Student Visa. This is because you should always have a visa that reflects your main purpose for being in the UK. If you travel in and out of the UK, you will have to explain your reason for re-entering the UK. If your main purpose has changed to study and you have a Tier 1 visa, the immigration officer has the right to cancel your visa and refuse you entry.
If your Tier 1 visa expires and you do not intend to apply for further leave under Tier 1 General, you can apply for Tier 4 (General) either inside or outside the UK - but please see below 'Switching to Tier 4 (General).
You can study in the UK under Tier 2 Skilled Worker as long as you continue to work for your employer. It is advisable to check that your employer is happy for you to study while working for them.
If you stop working for your employer in order to study, you need to apply for a Tier 4 General Student Visa, even if you have time left on your Tier 2 Skilled Worker visa. You can do this inside or outside the UK - but please see below 'Switching to Tier 4 (General).'
If you are in the UK as a dependant of someone with current immigration status in the UK, you can study.
If your visa expires and you cannot extend your stay as a dependant, you will need to apply as a Tier 4 (General) Student. You cannot do this inside the UK, you need to return to your home country and apply from there. Please also note below on 'Switching to Tier 4.
If you are currently in the UK as a diplomat, you are exempt from immigration control therefore you can study in the UK.
If you are working as a diplomat outside the UK, you can enter the UK using your diplomatic passport but this does not permit you to study in the UK. You will need to obtain immigration permission to study. The kind of permission you will need depends on the programme that you are studying at LSE.
If your spouse or your parent is currently in the UK as a diplomat and you are in the UK as their dependant, you are also exempt from immigration control and can study in the UK as long as your family member remains in the UK during your studies.
If your spouse or parent is a diplomat outside the UK, you will need to obtain student immigration permission to study in the UK.

Who needs a visa?
Can I study part-time with a non-student visa?
If you are in the UK with a non-student visa that allows you to study, there are no restrictions on the number of hours that you need to study. This means that you can study part time (not all LSE programmes have a part time option and there are no part time undergraduate programmes).
However, if your visa is going to expire during the course and you need to apply for a Tier 4 (General) Student visa, you can only study on a full time basis. If you are part way through a programme at LSE on a part time basis, it may not be possible to switch to full time. It is advisable, therefore, to only start a part time course if you have a visa that is valid for the duration of the course or if you are certain that you will be able to extend your stay in the UK with another non-student visa.
Switching to Tier 4 (General)
If you have to switch from a non-student category to Tier 4 you need to check if you can do this inside the UK or if you have to travel home to apply.
To be eligible for a Tier 4 (General) Student visa, you need to be studying on a full time programme.
Caps on time spent studying.
There is a cap on the amount of time that you can study with student immigration permission in the UK. This means that if you have previously studied in the UK you can only apply again for a student visa if this will not take you beyond five years at degree level or eight years at PhD level if you have already been awarded a research degree.
