Student Visa (F1, F2, M1, M2)

Hi everyone, mine is a complicated case. Mine is an IT company and I've been here for 4+ years. My company is headquartered in USA and they find me talented and require my skills in the USA from time to time. They applied for my H1B but it got denied in RFE, after two years they needed my expertise as an SME to meet with a client so they applied for B1 visa and it got rejected. They find me very skillful and make sure to pay me well and now want me to travel to the US on an L1 visa as they need my expertise there, they have tried hiring on site and hired a few consultants but they cheated the company, took the payment and never gave the deliverable. I however have the desire to pursue PhD in the us and have been waiting for the right time to do so. If the company applies for my L1 and it gets accepted I would go through it and apply for PhD later but if L1 is denied and I apply for F1 in the coming months, will it impact my chances of getting a visa as I have so many denials. Let me also mention that I do not have any intention to immigrate, I love my country and will want to settle down in India.

Please guide me, this crossroads is completely scaring me.
