What to do when arriving in Russia?

Upon arrival at the international airport, you will be asked:

• Fill in the immigration form:  one part is delivered and the other is essential that you keep it to leave the country.
• Register your visa: they  have to put a stamp on your visa in the establishment where you stay. Keep in mind that the cheapest hotels do not always offer this service. You may have to go to an agency. Another difficulty: if you want to visit several places in Russia, you will have to put a stamp on your visa in each accommodation where you spend three days or more.
