you dont have anything to worry about.since they are your kids and the DNA results proves that.i went for my interview recently.i was also asked for the DNA results to prove paternal relationship.i went to the lagos consulate in Nigeria cause i am a nigerian.i am now in the US.When i went for my interview i dint take a whole lot of documents with me cause the lawyer handling the case has submitted all the required documents but i took the photocopies with me.take some pictures you took with your kids including their dads.i was asked for some pictures i took with my dad.it just serves as an additional prove of relationship.i guess you have submitted your W-2 whatever ,i dont know what its called but i know its W-2 something and other tax related stuffs for you and your husband.if u have not take them with you and if u have take the photocopies with you.in my case i was asked for police clearance certificates but u r not goin to need it because your kids are not up to 16.it is required for applicants who are 16 and above.when i went for mine in nigeria,i went with my junior brother also who is 12.he dint need the police stuff.also i was asked to do some medical test.in my brothers case who is 12(his own is similar to your kids both under 16)he did some medical test.he did some physical examinations as in his teeth,mouth,and other physical parts of his body was examined by a doctor.also he took some vaccinations.tthe results of all these medical exams was taken to the embassy.in my case because i am 19,i did hiv and syphilis tests.the hospital we used was assigned to us by the us consulate.but dont worry about anything since u r not a risk to the US,and you pay their taxes your kids should not have any problems.i detailed all this for u because u said u r from Ghana and since i am from nigeria (both west african countries i guess the same rules should apply.)as i said dont be worried just be patient and do whatever you are asked to do.i too needed to be patient.i was almost tired too because of their stress but i just kept cool and it was at last succesful.i am now in the US.During my own too,this forum really helped me.thats why i am eager to share my experience with the people who are in the same position i was once.good luck to you and your kids.
