Anyone doing the process in Cuba I have a tip on the how your spouse/significant other can get their superpacket.
We were waiting about 2 weeks after the NVC approval was wired to Havana and my husband hadn't heard anything. I was concerned because he works all day and no one is at his house if the interests section were to call him to tell him how to get the packet.
So I started calling the interests section last Thursday, I tried to call 3 days (all day long, hundreds of times!) and couldn't get through. The Interests Section posts close to 10 different numbers on their contact web page http://havana.usinterestsection.gov/contact.html. but none of them worked, not even a dial tone most times.
So I saw cubanlovestory's post from months ago and faxed in a brief letter to 53-7-833-1084, just stating my case number, my husband's passport number and full name and that he needed an appointment to get his packet 3, they called him within 2 hours of sending the fax, que bueno!!! I finally got through by telephone an hour after he got the phone call (I hadn't talked yet so I didn't know that he made the arrangements yet) The number that finally worked was 53-7-834-4400.
Anyways, the girl was very helpful and told me that everything was taken care of and that my husband had made arrangements to pick up his packet 3 in a week.
So to anyone who is waiting to recieve superpacket instructions, start calling and faxing after about a week from NVC approval, it takes a while but it will work eventually, be patient and good luck!
