I'm close to sending in my I-139F but I have a few answers that I hope this community can clarify for me.

Part 2, Question 37-38.h: On the I-129F form it says to do 38.a-38.h if the beneficiary is currently in the US. On the I-139F directions, it says to provide the information regarding the beneficiary's most recent entry. My fiance is not currently in the US but had recently visited. Am I supposed to answer this question or not?

Part 3 Criminal information 4a-4b: I have two alcohol related incidents. One I was cited for, the other I was arrested for. These have both been expunged. I have court certified documents stating that these records no longer exist. I also have the expungement document with all the appropriate signatures. The only problem is that they wrote my social security # wrong. Should I still send the expungement document? Will this cause problems for me?Also, should I explain the entire situation of how I was arrested? Or would just listing the charges and dates be enough?

Last question - other names used: My nickname is a shortened form of my name (think Matthew-Matt). I sign my signature with this nickname and have it on some travel documents I'm including as proof. The same goes for my fiance. So for other names used, should we put out nicknames? Or is this only for a legal name?

Thanks in advance for the help!

Do I need to have a Japanese visa and stamp in my passport translated? They are mostly in English with only a few Japanese characters.

I also have a certificate from studying abroad at a college in Japan. The document is in both English and Japanese. Would this also have to be translated?

My fiance is Japanese but is currently on a working holiday in Canada. In Part 2, there is a part that asks for the beneficiary's name and address in their native language. We put down her name in Japanese, but what should we do about the address? It's a Canadian address so I would assume it would be ok to put English but I'm not sure...

Both my fiance and I have had multiple jobs and addresses over the last 5 years, so it doesn't all fit in part 8. Would it be better for me to make multiple copies of part 8 and fill those out, or just make a word document and type the info in there? 

If I should type it in a separate document, does anyone have an example?

I've been looking at this form and am a little confused about how to proceed. I have 2 alcohol related charges that have since been expunged. This doesn't fit the criteria of the "specified crimes," which require certified copies of court and police records.

Part 4.a of this section asks if I've ever been arrested and then 4.b asks me to "provide information." 

So I have to answer yes to this even though my records have been expunged? And do I have to have a certified disposition/arrest record for this? 

If I do need those documents, is it possible to have them mailed from the court? I live pretty far away.

Great, thanks for the info!

So she can do the interview at a US embassy in Canada then?

My Japanese girlfriend is planning on working in Canada on a working visa. We have talked about the K1 Visa in the past, and have decided to go through with it sometime in the near future. My GF will be working somewhere in Ontario (she's not entirely sure where yet, maybe Toronto?), and I live relatively close to the US-Canadian border, so this works out quite well for us. Anyway, I plan to propose to her during her stay in Canada. My question is: Can she do the necessary tasks for the K1 Visa while in Canada, or would she have to return to Japan to do so?

Additionally, I know this doesn't specifically regard US immigration, but does anyone know if it would it be ok for her to come to the US and visit me for a week or two, and then have me drive her into Canada to start her working holiday? I haven't seen much online regarding entering Canada by land to start their working visa program, and I wasn't sure if we could be given trouble over this at the border.
