"You will need a relatively high level position to qualify for EB-2, since there will have to be a masters requirement or 5 years of experience. To the best of my knowleddge, a Senior Accountant is the lowest end of experience levels (may just require a 4 year degree or a CPA). You will have to describe your position in more detail to get a better answer. To qualify for EB-2, you would have to be in a position more like an accounting manager (in a CPA firm), or a CFO in a company."
You're really lucky to get through EB2. Normally,only if the job position offered to you is a Sr Financial Analyst and it requires MS with 5 years exp ,you may qualify for EB2.
