hey yall so im going to apply for citizenship in 2 years and after that I want to file a petition for my mom. she came here on a visa and overstayed. but my problem is that I went to look at her passport which has the visa and theres an admission stamp from her country dated after her last admission stamp into the usa . she didn't leave .. we don't know if the stamp was a previous mistake. will this be an issue when the time comes for us to file. any input would be appreciated.
