I have a Bachelor's degree in Communications.
Pretty much useless on the Polish job market. Even more useless than in the States.
Also, given my prior experience, I know some rather basic computer science/programming skills and have a lot of experience in customer service (although, i'd like to avoid this industry if possible). I'm still relatively young (24)
At 24, you don't have "a lot of experience". You're a mere dilettante. Your rudimentary IT and customer skills and (presumably) native English may land you a job in an outsourcing center, if you're lucky to find an employer that is willing to go through the hassle of getting work permission for you, but you would be very dissatisfied with the wages. Poland is a great place to live if you have lots of cash. It $ucks big time if you don't.
able to quickly get through any additional schooling or certifications that may be required of me to better secure a stable (and comfortable) income.
That would be near impossible in Poland without advanced knowledge of the language, which will take you several years of extremely hard work and copious amounts of time to acquire.
Also, if you're looking for a stable and comfortable income, Poland is not the place for you. Competition is fierce (especially for non-EU citizens), wages are low, the cost of living relative to wages is high, and savings potential is abysmal. There are very few Americans for whom Poland offers viable career opportunities, and you are not one of them by a long shot.
Your best option would be to reschool in the US and get a degree that is actually useful on the job market. You wasted valuable time pursuing a degree in communications. If you want a stable (and comfortable) income, then study something with lots of advanced applied mathematics like petroleum, geological or biomedical engineering, or super math-heavy non-science fields like financial mathematics, financial engineering, econometrics or actuarial sciences (not useless non-math majors like finance, economics, business, administration or marketing). Non-math majors are practically useless nowadays, and basically enable you to flip burgers and stock supermarket shelves on the night shift.
We live in a technocracy, kid. Wake up, smell the coffee and get out your math book. Or practice saying, "Would you like fries with that, Sir?"
