LCA with level 4 wages and PERM with level 3 wages??

[AustinGreyson]

All,
My LCA (H1B) was filed under level 4 wages. With the new H1B wage rules, my required ages have jumped by 120%.
My firm was omegle xender in the planning stages of applying for GC (PERM). Can do file the PERM under level 3 wages or do they have to stick with L4 wages?

Thank you!
