Can I file for Attorney Certified Consulor Processing without current employment?

[I140toCounselor]

I got H1B through company A then got my I-140 approved through Company A on EB3 category. I left Company A and joined Company B on H1B. Then I left USA (abandoned my H1B and Company B) to get married in my home country in July of 2013. I have been out of US for about 8 months now and residing in my home country. However, my priority date for the I-140 from Company A became current in September of 2013. At this time, will I be able to use my approved I-140 from Company A to file for Attorney Certified Consular Processing of permanent residency at my home country? My spouse does not want to leave his job here in home country right away. My question is can I file for consular processing at my home country independently as in without a sponsorship/employment offer from Company A or B or any other company in US at this time because I have an approved I-140? Or must I have an employment sponsorship at this time and or until the time my permanent residency process is completed to be able to apply for the permanent resident status using Consular processing? Thank you so much!
