So, I am not sure how much of what the senior members said you understood! But I'll do my best to put it in simple wordings THIS IS NOT TO INSULT YOU IN ANYWAY!!!
Your wedding was done in court without your parents consent! Ok...the officer who interviewed you must have had other doubts that you might have not mentioned. What did you take for the interview in terms of proof of relationship or were you asked to bring that with you at the time?
What proof DO YOU HAVE to show that your relationship is genuine and the marriage was not just for PR purpose? Are both your nationality, culture, religion same? How did you both meet? Whats your past before this marriage? Whats hers? So you have to have valid answers and proof for all these if you get refused and you choose to appeal. Did you FULLY UNDERSTAND the questions that were asked by the interviewer?
