I had the interview today, everything went well, the old lady was really nice. Even though we got married less than 2 months after we met, she didn't ask many questions, yes, she believed us. She said she couldn't approve me today cos she didn't have the authority and had to let her supervisor to review, but everything went well including name check, so I will get the approval soon. She also explained the condition removal procedure in 2 years and citizenship application. So we went home happily, now I think I will just wait for the letter and GC.
