If you are planning on returning to your home country then you must check with the UK visa and immigration that your visa allows you to return to the UK after a period of time in another country. Please also note the effect any time out of the UK may have on future requests for settlement. You will also need to seek approval from your College/Professional Service and they will need to seek advice about tax/social security, etc. from the Global Mobility advisor.
Please ensure your Human Resources Business Partner and the International Immigration Advisor are aware you are on a Tier 2/Highly skilled visa. We need to notify the Home Office that your pay will be affected due to a period of leave.
