Doctoral students, postdocs and academic guests: residence in Switzerland

Are you coming to a Swiss university for a doctorate, a postdoc or as a guest? Then everything depends on your role: are you primarily in further education, an employee of the university or a visitor? This determines which legal basis applies and what work you may do on the side. The cantons handle individual situations differently, so clarify your case early. This article concerns third-country nationals; for EU/EFTA nationals the Agreement on the Free Movement of Persons (AFMP) applies, which makes access considerably easier.

1. Admission for further education (Art. 27 AIG)

A doctorate generally counts as further education. The requirements are specified in the VZAE:

• Financial means must be proven, in particular by a declaration of commitment with proof of income and assets from a solvent person in Switzerland, by confirmation from a bank licensed in Switzerland or by a binding assurance of sufficient scholarships (Art. 23 para. 1 VZAE).
• Personal requirements: No circumstances may indicate that the further education serves only to circumvent the general admission rules (Art. 23 para. 2 VZAE).
• Duration: Education and further education are generally permitted for a maximum of eight years; exceptions are possible for targeted further education (Art. 23 para. 3 VZAE).
• University: It must offer a guarantee of proper further education, the programme and duration must be defined, and the management confirms that the language and educational requirements are met (Art. 24 VZAE).

2. Working during the doctorate: Art. 40 VZAE

Unlike general side employment for students (Art. 38 VZAE: at the earliest six months after the start, a maximum of 15 hours per week), Art. 40 mentions neither a waiting period nor a maximum number of hours. It remains a discretionary provision, however: the authority examines whether the activity fits the specialised scientific field and does not impair the further education. The application is made by the university as employer.

3. Postdocs as employees

Whether a postdoc is permitted as further education or as ordinary employment can vary depending on the situation and the canton. If it is treated as gainful employment, the general admission requirements apply (Art. 18 ff. AIG), including qualification and maximum numbers. Anyone who has obtained a university degree in Switzerland and whose activity is of high scientific or economic interest is admitted under eased requirements (Art. 21 para. 3 AIG).

4. Academic guests

• Short visit of up to three months: Without gainful employment, a stay of up to three months within six months does not require a permit; a visa may be required depending on nationality (Art. 9 VZAE).
• Working in the lab or in teaching: This can be gainful employment even if it is unpaid (Art. 11 para. 2 AIG). In case of doubt, the cantonal labour market authority decides; doubtful cases go to the SEM (Art. 4 VZAE).
• Short assignment on behalf of the home institution: It may fall under the eight-day rule (Art. 14 VZAE). Check this in advance.
• Longer visit: Depending on how it is structured, as further education (Art. 27 AIG) with proof of financing or as international scientific exchange (Art. 41 VZAE: overall economic interest, application by an employer, maximum numbers, pay and working conditions, personal requirements, suitable housing).

The most common pitfalls

• Financing not proven in a binding way: A funding promise in prospect is not enough; a binding assurance is required.
• Working without a permit: Even “just a small” assistant job requires a permit.
• Change of role: Anyone who moves from the doctorate into employment needs a new permit (Art. 54 VZAE).
• The eight-year limit: Factor in the total duration of further education (Art. 23 para. 3 VZAE).
• Planned too late: Visa and permit take time, while the start of the semester and of the contract are fixed dates.
• Family: Bringing family members is not a given and in particular requires secure financial means, see Family reunification in Switzerland.
