Can an Electron's Angular Momentum Change by Absorbing Virtual Photons?

[scope]

i wonder whether an electron is absorbing virtual photons because it is in a electromagnetic field, would that mean that it would change its angular momentum by hbar?

An electron never changes its intrinsic angular momentum, its spin. (The direction changes, but not the amount.) That is a fundamental property of the particle. Certainly the total angular momentum can and does change under the influence of the EM field.
