From G cross-border permit holder to B residence permit holder — minimal v3 bridge

Effective date: 01.01.2024. Status: AI initial draft · v3-minimal · v4 extended, full coverage of cross-border workers.

What this is about

Anyone who holds a G cross-border permit — i.e. works in Switzerland but lives in the border area of a neighbouring country (France, Germany, Austria, Italy, Liechtenstein) — and wishes to move their place of residence to Switzerland legally changes from the G permit to the B permit (AFMP residence).

The procedure is generally straightforward for EU/EFTA nationals, as AFMP Annex I, Art. 7 codifies the right of residence for AFMP workers with employment in Switzerland. There is therefore no separate "G→B application", but rather an initial B residence permit based on employment in Switzerland.

Procedure outline

1. Relocation of residence to Switzerland: Conclude a lease agreement, register the change of address, adjust insurance policies.
2. Registration with the Swiss municipality of residence within 14 days of arrival (FNIA Art. 12 — see proc_kantonal_registration_14days.md

• Identity card / passport,
• current G permit (to be replaced by a B permit),
• Employment contract or confirmation from the employer,
• Tenancy agreement or proof of ownership of the Swiss property,
• Proof of health insurance (see below),
• biometric data will be collected on site.

5. Health insurance change: Cross-border workers are often exempt from the mandatory Swiss health insurance scheme (KVG) under the France-Switzerland Agreement (CMU-Frontalier) or another neighbouring country’s system. If they move their residence to Switzerland, health insurance under the KVG becomes mandatory (see framework/fw_social_insurance_and_permit_impact.md).
6. Registration of arrival is ordered — usually within 2–6 weeks.

Practical information

Obligation to notify job openings: Not applicable to AFMP nationals – automatic AFMP protection.

Quota restriction: Not applicable to nationals of FZA.

Family reunification: Spouses and children may also move to Switzerland under AFMP Annex I, Art. 3; the derivative B permit can be applied for at the same time or subsequently.

Tax implications: Moving the place of residence means that the person becomes liable for tax in Switzerland. The withholding tax for cross-border workers no longer applies; instead, ordinary tax assessment applies. From a permit perspective, this is irrelevant, but from a tax perspective, it represents a change in circumstances.

Road Traffic: Swiss driving licence exchange must be carried out within 12 months of taking up residence (FZG Art. 42).

Third-country nationals in cross-border employment

Holders of G permits from third countries are less common (essentially, these are cases from older cohorts and special cases), and the change to a B permit takes place under FNIA Articles 18-21 (employment of third-country nationals), with the obligation to register the employment and, if applicable, subject to quota restrictions. This file does not cover this process; see permits/permit_b_resident.md for the standard application process for a B permit for third-country nationals.

What this file is NOT

• no full coverage for cross-border commuters (see permits/permit_g_frontalier.md — postponed to version 4),
• no tax advice on changing residence,
• no recommendation as to the choice of canton of residence,
• no advice on the reverse path (changing from a B permit to a G cross-border permit).
