Rules applicable to obtain the resident permit
http://www.ne.ch/autorites/DEAS/SMIG/sejour-etablissement/Pages/Etats-tiers---Etudiants.aspx
No studies in Switzerland can begin without a resident permit. You will need :
UE/AELE students must register with the Neuchâtel local authority of population control within 14 days after their arrival in Switzerland to obtain their resident permit. They must also certify that they have taken out a health insurance and that they have the capability to financially support themselves. They must prove that they are enrolled in a university or a recognized graduate school. The resident permit will be valid for one year and extended every year until the end of the studies.
Students are allowed to work but no more than 15 hours per week. For additional working hours, they will be considered taxable and they will have to obtain a specific resident permit corresponding to their new status. Student’s spouses and dependent children are authorized to stay in Switzerland but are not allowed to work. The official website Portail Suisse provides all the addresses of cantonal authorities and local authorities.
Non UE/AELE students must include a study plan laying down their objectives and type of studies (Maturité, Bachelor, Master…). They must also provide a written confirmation from the school as evidence that they are authorized to attend school and that they possess the required language skills. Students from other countries requiring a visa must apply for a resident permit with the embassy of their country of origin in Switzerland or the consular representatives of their country. This resident permit application requires the school admission confirmation, evidence that the student can pay for his school fees and support his own financial needs, a written undertaking that he will return to his country of origin after his studies, and a curriculum vitae. The Swiss representation of the corresponding country will determine whether the applicant is proficient in the language required for his studies. The cantons are responsible for issuing residence permits. They will therefore provide detailed information regarding such procedures (where to submit the application? Which forms to fill out ? How long does it take ?...) See the list published by Federal Office of Migration.
You will go in person to the Neuchâtel local authority of population control and submit your resident permit application, complete with the address of La Résidence-Neuchâtel: Rue des Usines 37 – 2003 Neuchâtel.
