emergency:If my visa interview is scheduled for 7:30AM, can I get there at 10? Flight is delayed...

I am scheduled to go to the consulate in Shanghai for a H1b visa interview.
It is at 7:30 in the morning on 12-9-09. My flight today is delayed for a
day. I will arrive at Shanghai at 3:05PM on 12-8-09. I don't think I will
have time to pay the visa fee that day. Can I pay the fee in the morning
right after 9AM when the bank opens, and then go to the consulate after that
?????

Please help....Thanks!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
