Hi everyone. I am due for my DV2008 interview but would like to postpone it for a week. however I have tried to call the embassy through the number they have provided on the 2nd NL 0203753705 which always takes me to vioce mail and them cuts off. the other number0203636492 provided in the website for immigrant visas is never picked. I have ended up writing an email to consularnairobi@state.gov will it suffice? on the other hand the issue of evidence of support someone had said in this forum that a single pwerson does not require any evidence of support. Am single and I have an email from a permamnet resident of the US offering to host me. is this enough what is the experience of others? pliz help
