Kamakazee/Ron, I hope you might see my question here. In my case, it was received by uscis on may 27th and notice date is may 29th. When I called uscis on monday they said it has to pass 75 days from notice date to file an SR. Tomorrow i am planning to file an SR. Do we need to have a valid reason to file an SR or are we eligible to file an SR after 75days? I heard that there is no use filing an SR until 90days is that true?
