My American fiancé and I are just starting to look into the immigration process and trying to identify any tripping hazards we might encounter. I'm still using my previous spouse's surname, because I had done a legal name change rather than simply assuming his surname after marriage. Our divorce is recent but we'd been separated for quite a while. Is my use of his surname likely to raise eyebrows during the K1 application with my fiancé? Am I overthinking this?
