Global Mobility/International Working

Cross-border or overseas working is a complex area carrying several compliance risks, most notably the need to ensure the University meets its tax and social security obligations in countries of work and fulfils legal requirements in countries where work is taking place. Where there is a business reason for an employee or prospective employee needing to work overseas, it is essential that an expert assessment of their unique working pattern is first carried out in conjunction with the University tax team. An approval process must be followed prior to overseas working taking place in order to ensure the cost-effectiveness of such arrangements.

The University has an existing process to support the assessment and approval of instances of overseas working, which provides an approval form, and defines what level of overseas working would trigger the need to obtain approval. Instances of overseas working not reaching the threshold durations as defined by the University (typically 90 days or more spent abroad) still need to obtain Departmental approval.

NDM approval process

To supplement the University process, applications from NDM employees or line managers must be approved by the Department using the new process, details of which can be found below. It should not be assumed that a request to work overseas will be automatically granted as these arrangements include, in many cases, substantial additional cost.

If you spend time working outside the UK or established AAP locations or have any questions about this change, please contact HR (NDM ORC- / Experimental Medicine-

NDM Global Mobility Process




  •  New request arises for an overseas working arrangement of any duration.
  • This may be at the request of an employee or line manager, or recruitment stage.




  • This applicant completes this Departmental application form and, if the duration of the assignment exceeds
    the thresholds as described by the University, Section 1 of the University application form.
  • The Business Manager signs both forms to agree support in principle for the working arrangement and confirms
    the support of both the Unit Director and (if funded by GL) the DFO.



  • Following the assessment, and subject to continued support from the BM, Unit Director and DFO, the BM submits all relevant documentation to the NDM HR sub-committee.
  • Subject to support of the HR sub-committee, the application can then be submitted to the NDM HOD for approval.



  • The Business manager submits the University application form to the Tax team, to enable a formal assessment to be made of the costs associated with the proposed arrangement.
  • The Business Manager should also seek to identify additional (non-tax related) measures required to support
    the arrangement, as listed in the University process (e.g.: pension, insurance, risk assessment).
