How to fill BI visa form

[Sylus]

Hello,

Am new here. Please i need help on how to fill my form in a right way. Have gotten a visa invitation to attend a conference in the state.

So my question

1. Is it the person that send me the invitation that am going to us as my contact person in US or i should use the name of the organisation?
2. Have applied for student visa in 2007 and i was denied, i used my sister that is in the state as my contact person in US. So should i maintain my sister as my contact person , though am not going to see her or should i just use the person that sent me the invitation as my contact person in the state.

3. Should i mention my sister as my relation that i have there or i should say no in the field?


I will appreciate your swift response


Regards,
Sylus.
