US Immigration from Jamaica

My question is.. how do u register for the medical in Jamaica n how long before u get a date.. and the next question is, is it after the medical you shedule your interview with the embassy. I'm a f2a category n my interview date is next month..

Hi,

I received an email from the NVC today stating my K1 petition was forwarded to the Jamaican Embassy. It sounds like good news.

Hi everyone,

The apt my husband is currently renting and where we will be living together sent him a form requesting some information on my authorization to stay in the US. I'll be going on the CR1 visa and i'm not sure which of these on the list I actually have. These are the options they listed:

Form 1-551 Permanent Resident Card [Alien Registration
Receipt Card] (form includes photo and fingerprint).

Form 1-485 (Application for Adjustment of Status)

Form 1-94 Arrival-Departure Record (form does not
include. photo or fingerprint).

Other official USCIS document (describe in detail):

From what i've read once you enter on the CR1 you just have to wait on the SSN and the green card to be delivered. Would the greencard work in such a case like this as proof, and can the CR1 visa i'll be entering on be used in the interim, until the green card gets delivered, as I understand it can take awhile sometimes?

So sent off my i751 packet yesterday. I completely forgot to write in none or n/a in the blank fields. What are the odds this will be rejected? I tried searching but I couldn't find any instances of anyone's documents being rejected for this reason. The i751 is a shorter form compared to i130 or i485 so I don't think it should be a big deal. Please advise.

Does anyone know how long it takes to get an interview date after Dq for f-2a?
