And you might still owe on the difference, even with a tax treaty.

I have a DTV and I'm staying under 180 days this year because nobody knows what will happen.

@Greg *******

I will do a quick in and out DTV reset before I will ever do a DTV extension. It's too risky for the reason mentioned: requirements are open to interpretation by local IO. Best to keep your already approved DTV for 5 years IMO and not extend, just leave and come back in.

For us she needed that and a copy of my DTV and our marriage license.

Wife and I also had a great experience with the Vancouver consulate at the end of July. We had just been approved by them for Non-O visas based on retirement. Then the YT video came out of the interview with the immigration boss explaining all of (well most of) the DTV unknown's. The DTV sounded like a much better fit for us so we contacted the Vancouver embassy again. They told us that we could apply for the DTV and if we didn't get approved we could keep the Non-O's. If approved they'd just cancel our Non-O's. I immediately submitted an application (very similar to OP's) and 2 hours later was approved. 24 hours later wife was also approved as a dependent on mine. Very happy with the service in Vancouver.

@Klee *************

I was shocked when they approved my DTV 2 hours after I submitted it (end of July). Wife's which is just a dependent on mine took 24 hours.

@Craig ******

No.

Yes, this worked for me at the Vancouver consulate.

It depends where you are applying for it as they all have different requirements.

I haven't read "everything" but I've certainly seen the majority of people saying you will need to do a 90 day report, just like all the other longer than 90 day visas.
