Hi all, 
	 
	I am preparing to submit the N-400 based on the marriage with a US Citizen spouse. I have a couple questions. Can anyone help? 
	 
	(1) What's the application fee filing by paper? Is it $760, do i need to add other fee such as biometric? 
	(2) What's the physical presence requirement out of the three years rule (how many day)? Can I apply for the early filing (2 years and 9 months)? 
	 
	Thank you, 
	Yuteng
