我父母2015在中国自动放弃绿卡。 现在我爸爸去世了，我想给妈妈申请绿卡。 有几个关于I-130 和I-485的问题：
I-130
53. Was the beneficiary EVER in immigration proceedings? My answer should be: yes?
54。 If you answered 'Yes', select the type of proceedings and provide the location and date of the proceedings. (Removal, Exclusion/Deportation, Recission, Other Judicial Proceedings)
55.a. City or Town
55.b. State:
56. Date.
How should I answer these questions here? Thanks!
I-485
Part 5. Information About Your Marital History
my mom's current marital status is Widowed. Do I need to answer "Information About Prior Marriages (if any)‘
Thanks
