Thank You metroloy...
1. Yes I have found that I didn't use my passport number any of the form Ds-230 @ Dsp-122... bt I am not sure whether I used my passport no in DV 2010 application or not...
2. I renewed my passport and I have issued a new passport cause of changing my Current address... 2 years ago I was refused by US Embassy(Student Visa)... They have all of my information including old passport no... My new passport is referenced by old passport number... P.O.(Passport Officer) has mentioned the old passport number in the new Passport... and P.O. stapled two passports with each other...
3. Should I inform my new Passport No. to KCC or Embassy? I haven't got 2nd letter yet...
Case Number : ............. 10XXX
1.u don't need to include ur passport no until ur PCC & Medical is done. I think u can directly go to the interview with the new passport. U can consult to the experts about this.
2.Us embassy always keeps a very strong database . they will figure out anyhow that u were refused once. change of passport doesn't stop them knowing that . so u better prepare a good explanation to save ur *** this time.
Thanks @cheers.
