You should clarify as early as possible whether a stay at the host institution is subject to any conditions. For example, some host institutions ask fellowship holders to contribute a sum of money towards the institution's overhead. The SNSF does not cover any overhead costs incurred at host institutions abroad, however. The host institution may also ask for funds to cover the research costs. The SNSF can contribute a maximum of CHF 3,000 per year towards research costs if certain requirements are met. Fellowship holders who bring their own financial contribution for covering living costs should generally receive adequate support from their host institution; this support should encompass, among other things, infrastructure as well as any consumables. In this context, please take note of the "Information set SNSF mobility fellowships". Please also clarify your status at the host institution. Some host institutes demand that fellowship holders be officially employed at the institution. In such cases, it is possible that a large portion of the fellowship is spent on social security contributions. The amount that ought to be available to the fellowship holders to cover their living costs is therefore reduced.
