Understand, but not always you can do it through the embassy, because the petitioner should be living in that country, and not everyone apply for that kind of process. It’s good for you to read about it before doing anything.
Exactly, each person should read about it. I have lived here in DR for more than 3 years so I was able to file with the embassy. I hope your experience with online filing works smoothly!
I remember a case where the process was done through the embassy and it just lasted 6 months, but the petitioner was living in the beneficiary’s country. It means yes, it’s faster!
