Marriage In the US, then marriage in the Philippines prior to annulment

I need a legal advice. I am a Philippine citizen, i got married to my gf at that time in 2007 in the US. She is a US citizen. But it didnt work out, i didnt want to be a husband that waits for her at home just to be an eventual US citizen. Anyway, a few months into the marriage, i decided to go back in the philippines and we were not able to save the relationship. Fastforward to 2012, i have a new gf, we had a child, and we decided to get married. We got a civil marriage in city hall. My previous wife, already filed for annulment in the US but the final declaration has not been issued before i got married again.although she s aware of my current status and she doesnt want any involvement with me.  My question is, do i have to file for annulment for my 2nd marriage? Or is automatically void? Do i have to remarry my 2nd wife? Legally, i am married to her in the philippines.

Also, i myself has been offered a job in the US,  and i can bring my legal family with me.  Can i still use the marriage documents issued to my 2nd wife and i for the US immigration? Or do i need to marry her again? If i do have to marry her again, how do i get another cenomar?

I hope someone here can help me.
