To sum up, I'm military, married my wife in Japan after I came back to states (so she unfortunately was not on my orders) , submitted K3 visa, approved and they moved in, submitted I-751A and I-751 For my wife and her son on Sept 30 2022. We are still waiting on response, the last item we did was to do Bio metrics (fingerprints) taken for the son on June 12, 2023. The USCIS website shows an average of 25-29 months based off of what branch office you select.
I received an assignment to go back to Japan, I probably will not get my hard copy orders until September or October, with a report date of November.
My question is, if we move to Japan, and my son (age 19) decides to stay and we fly off to the Land of the Rising Sun, will he be able to continue to live in the US under the I-751A? (if the conditions aren't removed by the time we leave...)
My wife and son don't want to give up their citizenship, hence the visa. In Japan they are given until 21 for them to decide if they are going to stay a Japanese citizen or not. So we do not want him to rush things due to him living most of his life in Japan.
Thanks for the advice.
