bjnissa;
I attended the interview with my husband in 2007. The Immigration Officers are Canadian who work at the Canadian Embassy in Haiti. They come to Sto. Domingo for the interviews. The officer was a lady who was from Quebec. Her English was good and her Spanish was okay. He/she will ask your spouse which language they prefer the interview to be in either English or Spanish. My husband spoke both at his interview.
I have posted before on this, but just a recap. I attended the embassy for the interview. I showed my passport and was allowed into the waiting area with my husband. When the immigration officer saw that I was with him she asked if I was the spouse. She then interviewed us separately.
Hope this helps.
Sandy
