Hi, anyone knows what is the requirement to keep the PR status after we get green card. Someone told me we have to stay in US more than half year every year, otherwise, we may loss the status. While another guy said it is okay as long as we do not continuously stay outside of state for more than half year, which means we can virtually stay outside of the state all the time, as long as we have a entry every six month. I appreciate if you guys can share your thought on it.
