2. Intra-Company Transfer
If you are an existing employee of a multinational employer who needs to be transferred to their UK branch for training purposes or to fill a specific skilled vacancy that cannot be filled by a settled or EEA worker either on a long term basis or for frequent short visits. There are 4 sub-categories of Intra-Company Transfer:

ii) Short Term Staff – if you have been working for your organisation for at least 12 months directly prior to your transfer. You can get a visa of up to 12 months.
iii) Graduate Trainee – if you are a recent graduate recruit being transferred to a UK branch of your organisation for the purpose of training. (This route must not be used to fill long-term posts). You must be coming to the UK as part of a structured graduate training programme with clearly defined progression towards a managerial or specialist role within your organisation for a maximum period of 12 months.
iv) Skills Transfer – if you are employed overseas and are being transferred to a UK branch of the same organisation in a graduate occupation to acquire the skills and knowledge needed to perform your role overseas, or to impart your specialist skills – your visa would be for a maximum of six months.
