Can I get a 2 year business open visa

Hi, I know that the embassy issues one-year multiple entry M type, but I'm not sure whether it issues two-year multiple M type. I remember that the embassy does not issue such documents anymore. You can confirm this with the embassy. The documents required for one-year multiple entry M type are the same as those for regular M types, including your passport, a photocopy of the passport, a filled-out application form, a bare-headed color photo, and an invitation letter from your business partner.
