I am a US citizen but my wife is an Iranian citizen with US permanent resident status, which she obtained through our marriage. We were planning to travel to Iran to visit my in-laws. However, we are worried, with the recent news of visa waiver program changes, that there will be problems for us and that she will not be able to re-enter the US without a visa.
Will she be able to re-enter the US without having to apply for a visa?
Update: Just wanted to update this question with our experience. We were able to go to Iran and come back without any problems. As the answers to this question pointed out, the green card lets you return and the changes to the Visa Waiver Program has no impact if you are a permanent resident.
