number of photos ?

[java148]

As US citizen, I want to apply for green card for my mom who is currently in NY. I need these forms: G235A, G1145, I130, I131, I485, I693, I864.

Regarding photos, I read all of instructions, only I485 mentions that it requires 2 photos of my mom. I have searched this forum, it has different answers. don't know which one is correct.

Can you please help?

Thanks
