visa to go with hubby for interview back home

[wife 0]

Hi everybody, I've got a question for you that I hope you can help me with. Hubby and I are expecting to be taking a trip to Armenia some time next year for his visa interview, at which he will have to file the I-212 waiver. It's a pretty nervewracking thought as I guess you all know... but my question is, what kind of a visa should I (the USC) be getting in order to travel to Armenia? Right now we are filing the I-864 affidavit of support, and we're not really sure what happens next. I heard that they give you about a month's notice before the appointment, but we don't know when it's going to come. And will they send an invitation letter for me so that I can go with him?

And also, this might be different for different countries, but I saw on the Armenian embassy's website that they have this new e-visa, a 21-day tourist visa, that you can apply for online, no sending in your passport, and it only takes two days to process it (so they say...) Since I might be traveling overseas at the time when he gets the appointment I thought it sounded like a pretty convenient option - but I would love to hear how this is usually done and what you all think... I'm not sure yet how long I'll be able to stay there with him - hopefully longer than 21 days, in which case I would have to extend the visa once I'm there. Any thoughts?

Thank you,

wife
