Of course there Are lot of reasons to worry right now in this regard as there are 100 plus cases in the US currently.During that time they didn't respond back at all and i went via my own car from my current location and did the landing.Now i saw one post on the CIC official website stating that they might consider the extension request for such concerns on case by case basis. May be try doing that once if not come down to New York buffalo and take a car and do the landing that way may be. Its pretty scary right now all over.
