Does the waiver for meeting in person for the K-1 visa apply if my girlfriend lives in Iran (as there is a travel ban to there)?

The question

My girlfriend and I have been looking into ways for her to immigrate so we can get married here. There is typically a requirement for the K-1 visa that we must meet in person at least once within two years except in cases of extreme hardship or violation of customs. Would the cultural customs and travel ban constitute extreme hardship? Or would we need to find some way to coordinate meeting in some third country?
