My wife will be receiving her IR1 visa soon. Because of some unexpected plans, we may need to stay in her home country for another 2 years. We would like to go to the US after she gets the visa so we visit my friends and family. Can anyone tell me, if she enters the US and stays for a month, then exits the US, how long can she stay out of the country before there is an issue? I saw something about 12 months but I'm not entirely sure.
Thank you.
