US Immigration from Canada

We just sent in Packet 3.

What next? Do I just wait for packet 4 now? I thought I would need to pay a fee before submitting the Ds-160 but apparently not. When do I pay the Visa fee in Montreal?

Hello.

I'm still at 130 stage and since my husband is USC we filled out the form for myself and my 15 year daughter.

By the time we get to the interview she'll be 16.

I wonder if I'd have to fill out DS 260 for her and would she have to go through medical (my guess is yes on this one) and consulate interview in Montreal with me?

Thank you kindly

Can I take my own digital photo for the DS-160 and then bring 2 professional passport pics for interview?

Or do all the pictures have to be the same?

This situation has nothing to do with me but I'm asking for my best friend.

He's a Canadian citizen living in Georgia without status , Ritchie. He's 49 has 2 USC children from different moms. He originally received his gc at 22 years old, thru marriage. He sustained a back injury which caused him to stay in Canada and get treated there. He was too long in Canada, injured in the hospital and when he tried to come back to the US CPB took his greencard. This was back in 2009. The first marriage produced a son who's now 23. Because of the breakdown in marriage his son was adopted by the mom's second husband and carries the adopted father's name. Ritchie and his biological son Robbie have reconnected and have a relationship. Would Robbie be eligible to sponsor his father Ritchie?

TIA

Posting this question as a new post instead of adding to the super long thread so hopefully it's easier to find for others.

Toronto & Ontario are still under lockdown and my interview is Feb 8. I have my medical booked with Dr Mascarenhas, and his site says I need to have a photo with me. I'm not able to find any place that's open for photos.

Has anyone else had this issue and/or found a place in TO?
