Why are you guys insisting on paying for BIOMETRICS?? See what they say: 

$410. You must also pay an $85 biometric services fee, for a total of $495, if you are filing with one of the following eligibility categories: 

• (c)(33) Requesting consideration of Deferred Action for Childhood Arrivals (DACA);
• (c)(35) A beneficiary of an approved employment-based immigrant petition and you are facing compelling circumstances; or
• (c)(36) A spouse or unmarried dependent child of a beneficiary of an employment-based immigrant petition who is facing compelling circumstances.

There is no biometric services fee for any other eligibility category.
