US Immigration from Colombia

My fiancee's mother passed away when she was a child and she has no relationship with her father, she is not even sure of his full name, DOB or current residence. What she we put for both of these instances and will this raise a flag for us?

Hello and hope everyone is well.

Has anyone has seen any updates on their I-130 Petitions in February, March or April?

Last update on our petition was February 24 saying "In Process" and still "Under Review" so I was wondering if USCIS is completing petitions during these challenging times. Our priority date is November 5, 2019 and we're hopeful the I-130 is approved before July 2020 within the 7-8 month time frame.

All the best.
