If you're question is with respect to photoelectric effect, Then:
When energy is provided to electron then those electrons which gets sufficient energy to get away from nuclear force of attraction are emitted. The energy is large enough to let it free from attractive force being in particular shell. There is no need for it to go on subsequent shell by shell and get emitted to infinity (as compared to particular atoms dimensions).
