Me and my husband have already sent in the papers and I have received my work authorization. Now we are waiting for the interview and thinking about hiring a lawyer to be present at the immigration marriage interview with us. How much approx is it to do this? and how long do they need to familiarize themselves with our case?Is it also right that they can be suspicious just by looking at the application and papers/documents we have included or not included and based on that call us in for separate interview right away compared to as if it didnt look suspicious and would interview us only together? Thank you all so much for you help and answers!!
