Just want to share our experience. My spouse completed 4 semesters on H4 status as full time student. We applied to F1 status in July 2017 and got approved in February 2018 after 1 RFE on (1) Residence Abroad (2) Ability to pay (3) Proof of US residence (addresses).
Then my spouse traveled to India and applied for F1 VISA and got approved without any issues in October 2018. Questions/documents asked during F1 VISA (1) i20 (2) History of US immigration right from date arrived in US very first time. My spouse offered to show financial documents proof but consulate officer was ok NOT to check it. When my spouse applied for F1 VISA, there was only 1 subject remaining to complete degree requirement.
