How to verify the authenticity of a work permit
The most common variant, the authentication of a work permit is to check on the website of the FMS (Federal migration service). Visit FMS at the address http://www.fms.gov.ru/ and select in the top row on the right the tab "Inspection of documents". After you go to the next page, select the left under "Information services" tab, "Check the validity of work permits and patents". In the opened window enter the details of the work permit, which you need to check the code from the image and click "Send request". Checking work permits on the website of the FMS has one serious drawback – the data there may not yet be updated, and unless the permit issued recently, information about it may not be. So you need to know and the main features of the authorization for the work to determine its authenticity in appearance.
The original work permit, the first two digits indicate the year of issuance. For example, if a work permit is issued in 2010, the number must begin with the digits 10. If the value is different – before you fake.
Another way to check is to verify the work permit under illumination of ultraviolet light (UV-detector). Such a device is for those who works with cash. Genuine work permit is on the front side (where the photo) protection in the form of a thin oblique light green lines (the thickness about 0.5 mm) that is visible under an ultraviolet lamp. A fake may also have these stripes, but they are much thicker – 1 mm thick.
Another difference genuine work permit from a fake is visible under UV clearly marked on the reverse side of the permit. On the first line of the inscription is "FMS", and the second is "Russia". This impression happens in the fakes, but the edges of his blurred and fuzzy.
