I am a US permanent resident and sent my renewal application for my green card electronically. In the last 10 years got divorced once but never resumed to my maiden name and don't wish to so I did not change it on my renewal application. Therefore I sent copy of green card as initial evidence but thought hat the divorce decree was not required since I did not have to support anything with it since I did not want to change my name. Was I right? I need to know if I was supposed to send it anyway because is mandatory to advise change of marital status to immigration. I am planning to become US citizen in the future and don't know if this action could be considered as "untruthful". I have researched and can't find anything that says that is mandatory to advise change of marital status.
