Firstly, thank you for the comprehensive detail contained on your site. During the procedure, I consulted it countless times. When I did have questions, I found that calling migraines on 1800 on my local phone worked well and I was provided with patient, accurate assistance. Thankfully, I speak Spanish. I don't know if they provide information in English.
It can't be overstated that getting your foreign documents translated an apostilled before leaving your home country can save headaches, time, and courier fees. I underestimated the effort to find a translator. One of my documents was in both Dutch and English, which required two separate translations.
Updating personal data (actulizacion de dates) on the website I believe was important to do prior to submitting the visa. They reduced the time to update data from 30 to 20 minutes (as stated on your site). Because of this it took me three tries to complete it properly.
I obtained the biometrics appointment one day after submitting the visa request. Everyone was professional and the appointment took five minutes. They told me to monitor my email and that in 15 to 30 days I should get an answer. Hope my feedback helps and thank you again.
