Once the ALICE experiments starts collecting data, it will gather up to 4 PB of information per year. The data will be analyzed in centers distributed all over the world. Each of these centers might have a different software environment. To be able to use all these resources in a similar way, ALICE has developed AliEn, a GRID layer that provides the same interface independently of the underlying technology. AliEn has plugins to access different GRID implementations. The latest plugin that is being developed allows ALICE to communicate with the Open Science Grid (OSG). The rest of this paper will present how the AliEn-OSG works, the tests that have been done so far, and the plans for the future.
