On the I-134, I am not sure how would be best to answer this question:
"9. I have previously submitted affidavit(s) of support for the following person(s). If none, state none."

I have never submitted a I-134 affidavit of support for anyone.
I have submitted a I-864 affidavit of support for my X-wife. The I-864 was submitted in March of 2000. We divorced in Feb of this year, 2008.
Should I answer yes to this question and give her name even though the affidavit of support was not the I-134?
I want to avoid answering "yes" if it will cause any red flags, but also don't want to answer "no" if the Embassy will find this information and use the answer of "no" as a reason for denial.

The question is not "have you previously submitted an I-134". It's "have you previously submitted an affidavit of support".

Part of their reason for asking the question is to make sure you're capable of supporting everyone you've committed to support.

The fact that you've divorced your ex-wife in no way terminates your obligations under that I-864. The I-864 only terminates when you die, when she dies, when she becomes a citizen, when she leaves the country permanently, or when she accumulates 40 quarters of work for social security purposes.

I'm not sure exactly how they'll use the information, but they may want to make sure your income/assets are sufficient to support your ex-wife as well as your new proposed household.

It's possible that the old I-864 has terminated, either because your ex-wife became a citizen or because she accumulated 40 quarters of work credits. While married, she's credited with quarters that both she and her spouse earned, so it's theoretically possible to accumulate 40 quarters in five years.

At any rate, the question doesn't say to omit terminated affidavits of support, nor to omit affidavits of support that weren't I-134s. So you should list the I-864 that you've filled out. They'll probably find it anyway.

Yes, I do see your point, and I will list the I-864.

1 month after your divorce and you are filing for a K1?

Perhaps they were seperated for a long time before hand.......

This is personal and really is not relevant, but none the less.... I would like to make 1 point first though. When something doesn't make sense, in many cases it is because you don't have all the facts to see the situation clearly. This is the case in this situation.
The marriage was dead for 6 years and we remained together for the sake of our daughter. So, yes, 1 month after the legal divorce, but 6 years after the physical and emotional divorce.

Sorry to hear that. Yes here in VisaJourney it is really non of our business when it comes to such personal issues.

I just want to wish you a lifetime of love and hapiness with your future wifey!!
