Affidavit of support process is driving me nuts!

[Moe1998 0]

We are 6 persons in our family. Including the petitioner (my father)

My father applied for me(20 years old) , my 3 other minor siblings (less than 18) and my mother. The petition is approved and we paid everything all the fees and did the ds260. 

Now we have to submit documents to nvc through email. 

My question is my fathers income yearly is 28k. So it only covers 3 of us. Me my brother and him, he has a friend that will be a joint sponsor for us. 

DO WE PICK WHO THE JOINT SPONSOR CAN CHOOSE TO BE THE AOS OF? 

Is there any laws or anything? Can the joint sponsor be the aos of my mom and my 10yearold and 8 year old brother and sis? 

 

And how do we do the affidavit of support? And do we submit the joint sponsor papers with our papers? Or only who the joint sponsor is sponsoring? 

 

Like if he is sponsoring my mom, do we send her documents to the nvc, with the affidavit of support of who’s sponsoring her? my father or our friend the Joint sponsor? What documents does the joint sponsor needs to give us.

 

 

this process is so hard on us since we’re not very experienced with this kind of work and laws.
