Can i change my Green Card filing status from EB2 to EB3.

Hello,

My company applied for my H1B visa on my Masters Degree, few months back my company applied for my GreenCard on my MS degree "not sure if they applied under eb2 or eb3 category". My question here is can i ask my company attorney to file my GreenCard under eb3 category with my Bachelors Degree rather than my Masters Degree as being filed now, as i have not received my MS degree yet. Are there any issues to be concerned with the above scenario, any inputs you may provide will be much appreciated.

Thanks,
Tarun
