@farzanehlaw: A postmark does not determine whether USCIS considers a filing on time. For paper filings, USCIS generally looks at the date the filing is received. Some deadlines counted in days may move to the next business day when they fall on a weekend or federal holiday. Deadlines tied to a birthday or expiring immigration status may not. Filing early is the best way to avoid an unexpected timing issue. Questions about an upcoming USCIS deadline?
