Financial certificate

<p>I am an international student and I had to write the expiration date for my I-94(somethign that you get when you come to the states) but I didnt have my passport with me when I was staying with a friend this break..My boarding school keeps students passports for safety reasons
So I left it blank and just sent off finicnacial ceritificates like that . would this be a problem? T_T ?</p>
