Hi boss! Please i need you to tutor mi on the processes in involved in the whole journey of schooling aboard.

My brother just got his F1 form today.
He then called mi to ask for his visa fee (64k).
On the form the earliest admission date is 10th of December.
And the earliest interview date we can get from the embassy now is 20th if not beyond.
Please, i would like to confirm if we should go ahead for the visa fee payment. Thanks
