There isn't any. I've lost confidence in the system.
When I went to the embassy in Havana to pick up the second refusal, I was five months pregnant. I threw a pregnant woman tantrum so that I could go in and speak to an officer.
When I finally managed to meet with an officer who spoke some English, he explained to me that what wasn't written was that my case had been refused because I hadn't paid the application for permanent residence fee. The $1,200 fee was the issue. I told the officer that my husband was being prevented from seeing the birth of his child because I hadn't yet paid the $1,200, which I planned to pay shortly, and that this was why the case was refused.
He said that they were putting this note in the case file. He suggested that I submit the application for permanent residence and then apply for a visitor's visa. I asked him whether he knew how much each application cost. I told him that I had accumulated over $10,000 in immigration-related debt. This included all the paperwork and translations. It's incredibly expensive.
