Firstly, I want to get some things clear because I know everyone will say this otherwise:
We are seeing an immigration attorney for consultation soon
We've already printed out several documents to prove that my fiancée is not coming here with the intent to live here for the future until they get the K-1 Visa
Now. Heres the actual story:
Recently, when my my Ecuadorian, non US citizen, girlfriend arrived at O'Hare from her flight, an agent threatened to deport her; basically, because she had stayed previously for four months with me previously.
The agent was aggressive from the start and insinuated that my girlfriend was working illegally (she was not) because she had previously stayed here for four months instead of a month as it was stated on the original airplane ticket (when that happened, we simply decided to live together before she went back to college to see if the relationship was worth the effort of dating across countries). Also, it's important to note she was here three times after those four months, and that this was about 8 months ago. The agent eventually called me to verify that she lived with me and again was very aggressive.
I communicated the basics of our relationship with the agent, that we met in Ecuador, we have been dating for a year, that she's a student at college in Ecuador, and that we did not originally plan to have her live with me for four months but that then she decided to try for longer until she had to start school again.
At one point I communicated that I had sent the I-129F form to be reviewed, so that eventually, my girlfriend would need to come to the USA so we could get married, and the agent got extremely upset. She misunderstood what the I-129F form is and believed I was trying to file an adjustment status of citizenship for her (I-1485), instead of getting a K-1 visa. I tried explaining that she had the wrong idea and she told me that she knew more then me, and threatened to deport my girlfriend right then and there. Finally, eventually I got through to her and she let my girlfriend go but stated that she cannot stay any longer then a day after her flight to leave (around 3 weeks).
Her leaving then is fine but we are really concerned about what this means in the future for when she is trying to come to the United States from Ecuador to see me in the timeframe before the I-129f is approved and she is able to marry me. Again, we did nothing wrong and I'm really angry/sad that this happening to us.
What options should I pursue here? If anything happens the next time she comes here, is there anything we could end up doing? In general, I'm looking for advice on how seriously to treat this, I.E was this one officer who was mad or do we need to be super careful anytime she goes to the US for us to talk before the I-129F is approved.
