Yes, Indian citizens must have a valid visa to visit Switzerland.

Indians can easily apply for a short-term Schengen visa, which allows them to visit Switzerland for tourism, business, family visits, or other approved activities. It is valid for up to 90 days within a 180-day period. 

Yes, Switzerland is part of the Schengen Area; hence, with a Switzerland visa, you can travel freely to other Schengen Countries without needing additional visas. 

Note: The Schengen Area comprises the following 29 European countries: Austria, Belgium, Bulgaria, Croatia, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Italy, Latvia, Liechtenstein, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, and Switzerland. 

The fees for a Switzerland Schengen visa are as follows:

• Adults: €90 (approximately ₹8,260);
• Children (6-12 years): €45 (approximately ₹4,130);
• Children under 6 years: Free.

Note: Additional fees may apply if you opt for premium services, such as expedited processing, SMS notifications, or courier delivery of your passport.

The Switzerland tourist visa or a Schengen type-C visa is valid for up to 180 days, allowing a maximum stay of 90 days within this period. Depending on the visa type you are granted, single-entry or multiple-entry, you may be able to enter and exit the Schengen Area multiple times within the visa’s validity. 

No, Indians cannot apply for a Switzerland visa online. The process is entirely offline, and it involves submitting the visa application form and supporting documents at the embassy/VAC, providing biometrics, and paying the fee.

Yes, you can enter and travel to Switzerland with a Schengen visa issued by Germany. However, ideally, you must keep these two rules in mind:

• Entry point: You are advised to enter through the country that issued your visa. In this case, Germany should be your primary entry point into the Schengen Area. After that, you can travel to Switzerland or other Schengen countries. 
• Main destination for stay: You should spend the majority of your time in Germany, as you are required to apply for a visa from the country where you will spend the most time.

A single-entry Switzerland visa allows you to enter Switzerland (or the Schengen Area) only once. After leaving, you cannot re-enter, even if the visa is still valid.

Multiple-entry visa, on the other hand, allows you to enter and exit the Schengen Area multiple times within the visa’s validity period (as long as you do not exceed the 90-day stay limit within 180 days).

Yes, you can apply for a multiple-entry Schengen visa for Switzerland. Multiple-entry visas are typically issued for 1, 3, or 5 years, depending on your travel history and the discretion of the consular officer.

The 90/180 rule states that you can stay for up to 90 days within any 180-day period in the Schengen Area. These 90 days can be consecutive or spread across multiple trips. However, the cumulative stay within the Schengen Area must not exceed 90 days in any rolling 180-day window.

Understanding the rule:

• Rolling period: The 180 days are counted on a rolling basis, meaning each day you are in the Schengen Area, the 180-day period shifts forward by one day. For instance, if you stay from January 1 to March 31, you can return on May 1 but must leave by July 30 (the next 90-day window).
• Multiple entries: The rule applies regardless of whether you are on a single-entry or multiple-entry visa. If you leave the Schengen Area and re-enter, the days spent inside are still counted towards your 90-day limit.

Example:

• If you enter the Schengen Area on January 1 and stay for 30 days, you have 60 more days to use within the next 150 days.
• If you leave and return after 60 days, say on April 1, you can stay for another 60 days, completing your 90 days within that rolling 180-day period.

If you need to extend your stay in Switzerland for medical reasons, you can apply for a visa extension at the local immigration office in Switzerland. You will need to provide:

• Medical certificate: A certificate from a Swiss medical professional explaining the medical necessity for your extended stay.
• Proof of insurance: Evidence that your travel insurance covers the extended period.
• Financial proof: Proof that you have sufficient funds to support yourself during the extended stay.

Note: You must apply for the extension before your current visa expires and ensure that all documentation is thorough and convincing.
