I went to the interview on 03/11/2019 and my permanent residence was approved right there. I wasn't ask many questions, just the ones that are on the application (I think this is because we have been married for 15 years and have 2 kids). she told me that my residence card would be mail in 2 weeks and I checked my account and it says it has been mailed. I encourage all TPS holders that qualify for adjustment of status to apply as soon as possible while the TPS is still active. I sent my application on 09/10/2018 and it was approved on 03/11/2019. The whole process took only 6 months. Thanks to all of you for your help. It was very useful and I was able to do everything myself, without paying fees to anybody.
Thank you for your help TM92 everything you post was very helpful . I just send my application!!!!! I will keep it posted so that others in the same situation are encouraged to do the same.
