Hi
I did a K-1 visa last year, it took a long time and mine was at CSC instead of VSC. You pretty much have to deal with the grueling wait for the government to process your application.
The US Embassy in Chisinau is easy to work with, they are friendly and helpful. Once your long wait to get your petition has been approved at USCIS (DHS), it is sent to the Department of State and things get easier and faster.
The interview was simple and last only a few minutes, if you have a legitimate relationship, it will be no problem. It doesnt matter if she knows all the answers to all the questions, as long as she can prove to the interviewer that you have a legitimate relationship.
I dont think your wife can come here while waiting on a K-1 petition, usually the only K-1s that come here on visits are from visa waiver program countries
However, Moldova is a nice place to visit in my opinion. Do you like wine? Moldova was the Napa Valley of the Soviet Union, they have the largest wine cellar in the world, Milesti Mici, it has 55 kilometers of wine underground. You can take a tour in a taxi complete with a traditional moldovan dinner and wine tasting. In the winter, you can go skiing in nearby Bukovel Ukraine or several places in Romania. In the summer, you can go to the beach in Romania or Ukraine. Chisinau has several nice parks to visit and several shopping centers and outdoor markets. There is a nearby park on the Dniester River.
I would NOT suggest using a lawyer, I would suggest instead you carefully look over the guides on this website and read the instructions carefully before submitting the forms.
If you have any questions about Moldova in particular, let me know.
Good Luck
