US Immigration from Sweden

My fiancee (who is a US citizen) and I are filing the I-129F form but we're stuck on the part where she is supposed to fill out her employment history for the last 5 years. She has had 1 job for the past year but prior to this job, she had a bunch of short term jobs where she stayed for a few weeks-months. The problem is, she doesn t remember every place she has worked at nor does she remember the exact dates.

How important is this? Does the employment history have to be 100% correct or is it okay if she misses to list a couple of short term jobs? It was all warehouse jobs or fast food jobs btw.

I know it looks like a lot, but the questions are pretty simply guys. Sorry for the trouble.

I've done a petition for my parents to bring them to USA.
i130 & i867 which I THOUGHT would be an instant greencard if/once approved.

1)
But it seems they are getting a visa
So, this is not a greencard interview, it's a VISA interview am I understanding this correctly?

2)
So the interview they got at the embassy, is that a good sign? Does this mean it's as good as approved (IF the paperwork are all done and correct) ?

3)
Also, since it's not a marriage based petition (Where they have to prove marriage is real), and since they have ALL papers and evidence that I'm their son etc, will they still grill them with question ? or it's just a formality and gather all documents? I'm just wondering if they are going to be bunch of questions

4)
So if it IS a visa application, is it wise for them to say that they are moving to US? Or should they say that they're only visiting and IF move only they get their greencard?
I'm just not understanding I didn't apply for a visa for them to visit, I went through immigration to do a petition for them to actually move :S

5)
So when they get to US using their visa, can they apply for greencard right away?
If so, what form will I be filling?

Above link states:
"Original or certified copies of birth certificates for all children of the principal applicant (even if he or she is not accompanying)."

Of course they need MY birthceritificate.

Though it doesn't make sense for them to bring birth certificate for ALL my siblings who are not in the petition even, it does state ALL children, right?

Thank you !!!!!!!

Think I got most of this stuff covered before my parents Visa interview at embassy. I'm a bit confused about few things though

Q 1:

"If you are married: Your original marriage certificate, English translation, and a photocopy."

"Your original birth certificate, English translation, and a photocopy."

So...the ORIGINAL document, PLUS translated.. I Got that. but...PHOTOcopy? what the heck? photocopy of what?
Are they asking for ANOTHER copy of both so they can keep it? If so of the english (translated) or the original?

Q 2:

Both my parents got their interview at embassy same date and same time. Will they most likely be interviewed together? or separately?

Q 3:

"The appropriate Form I-864 Affidavit of Support for each financial sponsor along with a photocopy of the sponsor s IRS transcript or most recent U.S. federal income tax return, and any relevant W-2s."
So with the i864 they asked for a TRANSCRIPT of my tax returns. So for the interview, they need the 1000000 pages tax return instead and not the transcript that I can download from IRS which is only few pages?

Any advice at all is appreciated. Thank you

My parents appointment at US embassy in Sweden is coming up and the vaccine is the only thing left and it has turned out to be the MOST difficult!
I can't emphasize how many countless hours I spent on the phone and driving around to clinics & still not having any idea what to do.

FYI: My parents are both above 65 years old

On this link: https://www.cdc.gov/immigrantrefugeehealth/panel-physicians/vaccinations.html

it says require Varicella. But I don't know what kind. I've been told there's AT LEAST 3 different varicella types:

Varivax, Shingrix eller Zostavax

I know this might be a bit medical but..if anyone knows, please do let me know.

also, since Varicella is chickenpox (and my parents have had vaccine for it many years ago BUT they do not have the proof anymore), do you guys think there's a chance their visa will be denied if they don't provide evidence of anti-bodies or vaccine proof ?
I been told this should not be given to immune compromised people which they both are
Thanks in advance

1st of all, I want to thank everyone who helped me out during this process. I seriously would have never been able to do it without this forum.

I thought after the i-864 forms etc, the difficult part was over. HOLY (remove), it definitely is not.

I got e-mails about them having an interview at embassy May 16th just days ago.
Please, you do not need to know the answers to ALL questions in order to respond. Any help is appreciated!

Q 1:

After this interview, do they get a greencard right away? Or do they get a VISA first ?

Q 2:
If they get a VISA and NOT a greencard to start with, how long does it usually take to get a greencard after their Visa?

Q 3:
My parents usually go to doctor 3 times a week for checkup. They will have $0 US income. They do have some small savings but I was wondering about health insurance. They are both over 65.
I know Medicare require u to have worked for at least x years to qualify. Are there any good zero cost health insurance in US (california, Los Angeles) that anyone knows of ?
Medical MIGHT work, just wanted to see if there's any other recommendations?

THANK YOU !!!!!!
