hello dakonej,
I wasn't allowed to send you a private message, so I hope this information is usefull. My husband is salvadoran with a Canadian citizenship, as well as our sons.
We sent everything together, we made a big package of documents.
With the applications, we send:
Original birth certificates from me and our children, translated and a lawyer certification of the translation
Our wedding certificate
Police record from PNC
Certification of Centros Penales, easier than PNC
My husband and my university and MBA Diploma
Letter in english of some close friends that can certified our relationship
Pictures year by year of our family, in holidays, with friends, relatives, etc My husband made like a collage with pictures and a description of them with dates.
Complete medical exams.
My husbands divorce certificate, he was previously married.
Emails between you two with dates or some love letters with date.
I don't remember what other documents are required in the application.
I was very specific providing details of our relationship, our wedding ceremony, how I met my husband, etc. because I wanted to minimize any doubt of our relationship if they can have any.
Be very carefull with your lifetime description, so that you do not have any gaps of years or months in the application.
Always tell the truth.
My husband is in Canada and we hire some lawyers. They submitted everything to Misissauga so we can start the sponsorship process. After we got the sponsorship approved, the Mississauga office sent everything to guatemala. We received a notification that our application was received and then they sent an email asking for my passport so I deliver it personally.
I don't know if an interview is going to be necessary, but I if it is, I think it will be better to do everything in Guatemala because in El Salvador, they only transcript the interview and send it to Guatemala. Guatemala does all the process, El Salvador can receive the papers but they are sent to Guatamala.
I hope this can help. Sent everything together, and be very consistent with your lifetime.
Paola
