I have already bought an interrail promotional global pass and paid for it. However, afterall, I found that probably I should buy Eurail pass (I am living in Ireland as an exchange student from Hong Kong, but my course only last for 11 weeks here. Therefore, I did not apply any visa or residency of Ireland.)

Here are two questions:

1. Is it possible to change my interrail promotional global pass to eurail global pass? (I can pay the difference)
2. How strict are the residency checks for Interrail passes for non-EU citizens in these days? If I could not change my interrail pass, I would like to try to use my interrail pass to travel in Euro.

P.S. I know our passport will be checked in the train. But how about the proof of residence?
