TLScontact in Bangkok: Switzerland uses TLScontact for visa submission in Bangkok. Book an appointment and prepare two sets of application forms (Swiss require a signed form and a copy). Swiss appointments are generally available, but still plan a couple of weeks ahead in case.
Local guarantor process likely: For private visits, the Swiss Embassy often triggers a guarantee process with the cantonal authority. Shortly after you apply, your partner in Switzerland may receive a letter/email instructing them to go to the local Residents’ Office or Cantonal Migration Office to sign a financial guarantee and show income proof. This is normal for Switzerland. Make sure your partner is aware and ready to act quickly. Your visa issuance might depend on them completing this.
Invitation letter & relationship proof: Include a warm but clear invitation letter from your Swiss partner stating that they invite you to stay with them, and any relevant details (relationship, planned activities, promise that you will depart on time). Attach copies of their Swiss ID or permit and proof of address. Swiss authorities will expect evidence of a real relationship: provide photos of time spent together and communication logs if possible. Note: A case where a Thai applicant had never met the Swiss partner in person and had weak ties was refused – so if you haven’t met physically, consider meeting before applying, or be prepared for scrutiny.
Financials: Even if your partner will cover expenses (and likely sign a guarantee), still show your personal bank statements. It helps reassure that you have some financial stability. The Swiss require at least CHF 100 per day if self-funded, but if a guarantee is provided, it covers that requirement. Still, the embassy likes to see you’re not completely without funds.
Return ties and intent: Switzerland is strict but fair. They particularly look at whether you’ll return. Provide employer letters, proof of any children or family you care for, and perhaps a return plan (e.g., “I have to resume work on X date, as per employer letter”). The decision often comes quickly after the guarantee is done. Many couples get Swiss visas fine as long as the above steps are followed. Just be honest and thorough.
