H1B->F2->H1B transfer

Hi,My PERM is filed on 2nd April’2018 and my H1B is getting max out on 15th July’2018. As per current processing time I believe my PERM may not be approved before my H1B gets expired. My wife is currently on F1 VISA.I have following queries.1. I am planning to move to F2 VISA when my H1B is getting expired but F2 processing time is around 4 months so can stay in US on F2 receipt ?2. Should I fully use my H1B period(till 15th July) or should i keep few days on my H1B so I can use it to extend it if my I140 is approved ?2. Can I extend my H1B on F2’s receipt if my I-140 is approved?3. What are the chances of F2 approval considering my immigration petition(PERM/I-140) is pending ? 4. I live in California. Can I renew my driver’s license on F2’s receipt?5. My company is very small (less than 10 people) but my pay is well above wage Level 4 and I have 10+ years of experience. Will it be difficult to prove their ability to pay if I am not working when my I140 application is submitted while I am staying on F2?I would really appreciate your help in this matter.Thanks,
