I applied for AP in first week of October. Accidentally I missed some section of the application form and my form was sent back. Then I send it back. USCIS received it on November 6 2017 and the case is still pending. I already bought ticket for end of December for travel. I am worried if my AP approval won't be approved by end of December. My fiance is going through some treatment. Is there a way that I could use this reason for expedite my application and if so what are the steps that I need to follow? Do I need to hire an immigration lawyer? Please advise!
