You can only transfer the warranty if you upgrade it (at extra cost) to an onsite service plan, and only if the model in question is sold in Romania.  Since all service and support in that part of the world is through independent dealers, not Dell directly, you would also need to find a dealer willing to service a system it did not sell -- that part may be the most difficult. Translation:  any warranty work is very likely going to necessitate returning the system to the US.  Be sure you register the system with Dell so the warranty is in your name.  
I just bought an Alienware laptop from Amazon. The laptop is an Alienware m15 R7. The laptop model is available in Romania where I live but the exact configuration for it does not. Is the warranty still viable in that case?
m15 R7, Amazon, Dell warranty?
