Helping Ecuadorian Fiancee get US residency

Does anyone have any experience with helping their fiancee get residency or a work visa in the United States. What has been your experience?

We've known each other for 5 years and already have a 1.5 year old and another on the way. Is petitioning for the Fiancee visa the right way to go?

Thank you in advance for your suggestions!

I went the alien fiancee visa, but it was 25 years ago. It wasn't easy then and probably harder now.  You can apply in the United States for a visa to bring your fiancee to the US to marry.  It is a long and involved process witha ton of paperwork. Here are two sites that might help.

One of the things you will need to have is a letter of support for future spouse and a job to prove the ability to provide said support.

Good luck.  STATE  and VISA JOURNEY
