If I am reading this right, your "husband" was petitioned by an american citizen so she would have had to have been his "fiancee" but in the meantime he still had you as his girlfriend in your own country and you subsequently got pregnant and he married you all the while still going through the immigration process with an american citizen who I presume still believed him and that he loved her and was free to marry her.Am I correct so far???
And then he went through the interview but married you after his interview for immigration at the US embassy, following on from that he entered the USA as if he was the fiance of the US Citizen, carried on as though nothing was untoward and got his green card and now you want to know if he can petition for you and your daughter, is this also correct and if so what the hell happened to his US fiancee? why did he declare he was single when in actual fact he was married to you, a native of his own country.
As to the greencard, that is definitely too quick for a K1, or was he married to the USC in the first place.??????
Whichever way you look at it, which I must admit from your post is so confusing, it all smacks of fraud to me and if it is as I have stated above, I think you are both in for one hell of a shock when it all comes out.
Please correct me if i am wrong or try to make your post that much clearer.
