Yes, a Belgium visa allows you to travel freely to other Schengen Countries without needing additional visas. However, when applying, you must keep the following two key points in mind:

• You should clearly state your intention to visit multiple Schengen Countries and provide a detailed itinerary that covers your entire trip.
• Make sure your first point of entry is Belgium or that Belgium is your main destination, as this will align with the requirements of the embassy where you are applying for the visa.

Yes, you can enter and travel to Belgium with a Schengen visa issued by Austria. 

However, it’s advisable to spend the majority of your time in the country that issued the visa, or it should be your first point of entry into the Schengen Area. For example, if Austria issued your visa, you should ideally enter the Schengen Area through Austria or spend the most time there. After that, you’re free to visit other Schengen Countries like Belgium. 

A single-entry Belgium visa allows you to enter Belgium (& the Schengen Area) only once. After leaving, you cannot re-enter, even if the visa is still valid.
A multiple-entry visa, on the other hand, allows you to enter and exit Belgium (or 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 Belgium. Multiple-entry visas are typically issued for 1, 3, or 5 years, depending on your travel history and the discretion of the consular officer.

Note: Despite having a multiple-entry visa, you can only stay for a maximum of 90 days within a 180-day period.

The 90/180 rule is a crucial guideline for travellers holding a Schengen visa, dictating how long they can stay within the Schengen Area. It 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.
• Tracking your days: It’s important to keep track of the number of days you’ve spent in the Schengen Area during the last 180 days. Overstaying can result in fines, deportation, or a ban from re-entering the Schengen Area in the future.

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

• Medical certificate: A certificate from a Belgian 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.
