Work Study Visa
All foreign entrants to India need a valid and relevant visa.
Indian business visas are valid for between three months and one year or more with multiple entries. However, the period of stay in India is limited to six months each visit. A letter from a sponsoring Indian company will have to be submitted, along with an introductory letter from your own employer. Business visas can be granted for single or multiple entry and allow applicants to travel to India in order to pursue business activities, excluding employment, such as attending meetings and business conferences.
Those applying to work in India need to obtain an employment visa. Work permits, or Indian employment visas, may be issued to skilled professionals or to applicants filling a specific role. The requirements for work permits are loosely defined and at the discretion of Indian visa services, but you must have one in order to work in India. Although work permits may be obtained by either the employer or the employee, employers usually take the lead in submitting applications.
