Agent to Appraiser

[Sarah Grise]

Hi all! So, I am a licensed real estate agent in Pennsylvania. I am not sure if each state has different laws when it comes to this, but...is it possible to be a R.E.Agent *and* an appraiser? I am wanting to get into the BPO field, however in PA I must hold an appraisal license to do so (and get paid at least). 

If I obtain my appraisal license, can I still continue my work as a R.E.Agent?
