Yes i did send an invitation to the other adult, the other adult need to accept and start the application on his/her end and after completing all the document you can now submit all together.I noticed you applied for 2 adults. Did you send an invitation to the other adult, or did you apply separately? I sent an invitation to my spouse and completed everything (although we haven’t submitted the application yet), but the status still shows "invitation pending." My spouse has already accepted the invitation, but there was no prompt to answer the secret question during accepting invitation. I’m a bit confused about that. Could you please share how you went about it?
