no extra documents needed just extra payment for urgent processing, I think its extra $120 for one day processing, I'm not sure with the exact amount but I'm 100% sure it will cost extra if you want it urgent.. if you don't go within 2 weeks, I suggest just apply in person regular peocessing it will take only 7-10 business days, I received mine within a week didn't pay extra for urgent.. but of course if you want it asap then do it in person with extra payments, guarantor ready to answer their phone call and show them your airline tickets..best of luck
