Luxembourg offers several types of visas depending on the purpose of travel. The main categories include the Short-Stay Visa (Type C), which allows visitors to stay up to 90 days for tourism, business, or family visits within the Schengen Area; and the Long-Stay Visa (Type D), issued for stays longer than 90 days. The Long-Stay Visa includes different purposes such as the Work Visa for those with a job offer from a Luxembourg company, the Study Visa for international students accepted by a Luxembourg university, and the Family Reunification Visa for family members joining residents or citizens of Luxembourg. There is also a Business or Investor Visa for entrepreneurs starting or managing a business in the country, and a Research Visa for scientists or academics engaged in research projects. Each visa type has specific requirements, but all applicants must provide valid documents, proof of purpose, and evidence of financial stability.
