The International and Study Abroad Office (ISAO) will be moving to the Friston building - the new temporary building on the northern edge of the Science car park - during the Christmas break.
Currently based in the Mantell building, the ISAO, which comprises international students' support and study abroad, will move across the road during the week beginning 14 December.
The office will remain open in Mantell until 4pm on Friday 11 December (the last day of the autumn term). It is likely that services, including telephones, will be unavailable until Wednesday 16 December at the earliest, although the office may not be fully operational until after the Christmas closure on January 4 2010. Following the move, telephone numbers and email addresses will remain the same.
Head of International Students' Support, Sara Dyer, said: "We are looking forward to current students and staff visiting us in our new location, and to welcoming the new visiting and exchange students and international postgraduates who will be arriving at Sussex in January."
The Friston building will also be home to the School of Law, Politics and Sociology, pending the construction of the new academic building at the centre of campus, due to begin in mid-2010.
