Pay for both filled forms or only one ?

[Oldillyrian 0]

Hello . 
I am filling an I-130 form for my father and mother , i know they need to be separated forms . My question is , do i need to pay for each petition ($535 for one and $535 for the other which means $1070) or only $535 for both petitions ? 

And also the forms G-1145 and G-1450 for email confirmation and online pay , where should i attatch them , together with one of I-130 forms or attatch to both forms ?
Thank's in advance .

two separate petitions, two of everything, you can send them each in one package and then put them together in one big envelope since they are going to the same place

 

two separate checks or money orders, even if you send them together, they still could be split up and managed by two separate employees, so they have to be treated as separate, and each have their forms, documents and payments

I am about to send my i-130 petition for my parents next week. 

USCIS website says  -  " Mark the envelope and the cover letter with the nature of the submission. For example, Original Submission, Brief for an Appeal, or Response to Request for Additional Information."

                                     -  " Mark the envelope and the cover letter with the form number. For example, I-129, I-130, I-690 or I-698."

Do you have to write cover letter with your petition ?

So you also write the form no like i-130  on top of the mailing address ?
