Hi again,
YES IT IS ACCEPTABLE, I did it so.
First I sent my forms and photos via mail (DHL) but despite their (DHL) successful delivery report, KCC didn't receive my package, i don't know why! and then i asked them to know what i have to do now? and they answewred me: "mail or email them again". Secondly i emailed my forms to KCC and they RECEIVED my email this time and my case is processing now.
All you have to do is:
1.Download Form DS-230 (Part1&2) and Form DSP-122
2.Scan your Barcode sheet and photos (original photo jpg files are better than scanned)
3.Complete the PDF Files e-forms (NOT E-FILLING) 230 for yourself and your accompaning family and 122 just for yourself, save them and make sure that its properly saved (Remember to paste your Scanned Signature and your own language written name on your files)
OR if you are not completely familiar with PDF files the best way is:
Fill them out and sign 230(P1) with your regular signature and scan them.
4.Send an email to KCC including following files: (a.)form 230 for all the family(PDF file or scanned) (b.)form 122 for yourself(PDF file or scanned) (c.)your scanned barcode sheet (d.)an appropriate photo file for you and family.
you may tell them in the email that i have sent my package but you didn't receive it so these are my forms and photos.
As i told you before don't be in hurry.Complete them with patience.make sure that your infomation (Names,spellings,birth dates,signature etc.) is completely correct and matched to your other document (passport, education, birth & marriage cert. etc.),GOOD LUCK
