Once you login, you'll be required to pay some fees $425 if I remember correctly(mind you you can't pay with a credit or debit card, it has to be a savings or checking account).

If you being able to work ASAP is a priority then k1 is not for you- get married and file CR1. 
if you go the k1 route expect it to take at least 4-6 months. You’d want to get married ASAP and then file adjustment of status and employment authorization document.

With IR-1/CR-1 can immediately work from Day 1: https://www.uscis.gov/i-9-central/temporary-i-551-stamps-and-mrivs SSN is not required for starting work:
 
K-3 is very rare; in fiscal year 2019 only five were issued worldwide. One in Tegucigalpa: https://travel.state.gov/content/dam/visas/Statistics/Non-Immigrant-Statistics/MonthlyNIVIssuances/October 2018 - NIV Issuances by Post and Visa Class.pdf Page 95
And four in Ciudad Juarez:

Also, temporarily leaving the US after filing AOS doesn't abandon the process for those adjusting from K-3; 8 CFR § 245.2(a)(4)(ii)(C) https://www.law.cornell.edu/cfr/text/8/245.2
 

Can't say I've ever heard that before...or see evidence of it here on VJ.
 
Most cases that I've seen that take "longer than average" for approval have to do with where the foreign spouse (or fiance, for K1) is from or issues with documents filed (RFEs). 
 
My husband and I did the K1 route. We don't regret that choice, but from an objective standpoint that CR1 is better in a lot of ways. 

You can marry in the US and do a CR-1 (presuming -- as is likely if your fiance(e) is from Europe, as most European countries are part of the Visa Waiver Program, and most people from VWP countries are eligible to use it -- your partner can visit the US legally); it's just the non-US citizen has to return to their country after the wedding.
 
Coming to the US on a tourist visa and with intent to marry is not illegal or fraud. Coming to the US on a tourist visa with intent to marry and adjust status and stay is fraud.

My boyfriend and I are going through the same thing as you right now. We are contemplating K1, CR1, or breakup unfortunately. We have been doing long distance between the USA and Europe for 6 years and thought he was going to be able to transfer here through his job, but that fell through. Here’s the hard facts- the K1 visa is quicker in that you can be together sooner, but it will still take 6 months to 1+ years to be approved, average about 9 months to be approved. Then when you are in the USA you will need to get your work permit which will take about 6 months. You will not be able to do any resume building activities. Like you, that is not okay with my boyfriend as he wants to be able to work and thinks that not working will have a negative effect on our relationship. The next option is CR1- you need to get married abroad. You need to look into the country you want to marry in bc some have specific visas and/or paperwork you need to have to get married (again a waiting period). Then afterwards you apply for a CR1 visa. This will take 1-2+ years to be approved. How long it takes is really on multiple factors and luck. My boyfriend met with a lawyer yesterday and was told that the quicker cases are for those who as the foreigner already had a previous investor visa or were in the USA previously on a H1 or L1 visa or for those who have been married for a longer period of time. In my case, being a US citizen working and paying taxes and will be newly married, it would take on average 1.5 years. After that time, he has the green card in hand and can work. Both options completely suck. I hope that helps. Best of luck to you two. I know it’s really hard  

Marry and go CR1, stamp in passport serves as a temp GC and enables you to work from Day 1.

no, you will not be able to work until your have an EAD or greencard. As others have said, that can take anywhere from 6-12 months. sometimes a bit quicker, but i wouldnt count on it.
 
this is why the petitioner has to meet income requirements (which i feel are way too low, but thats not the topic here), so that they can SUPPORT their partner during this time.
 
a cr1 is the better option is working fairly immediately (generally within a few weeks) is important to you. the additional time it takes is fairly minimal at this point.

You are correct, you can NOT work until you have the work permit which takes 4 - 6 months. So you will be sitting at home waiting for months to work after you arrive. Not only that, you can't leave the US (if you get home sick) either until you get travel authorization. And that is taking 4 - 6 months also. And this is why many agree that the K1 sucks big time.
 
If you really think about, for some that want to work right away, the spousal visa is a better option. People get so sold on the K1 being faster (and it is only faster by a few months) that they overlook the huge disadvantages of it. If you are coming from a Visa-free country like Canada, a K1 may not make sense. Because if you do the spousal visa, you can get married in either country, then file the spousal visa, and, yes, you have to wait several months before you get the visa, however, you are still free to come to the US for visits during that time. You can't do that with the K1. Once you enter on a K1 you have to stay here until you marry, adjust status, and file and receive work and travel authorization. Plus, the adjustment of status from a K1 cost $1200. You don't have to adjust status on a spousal visa so it is less money.
 
P.S. The others are correct, the K3 is dead. No point in even considering it.
 
 
 P.P.S An SSN is NOT authorization of work! Those who say they were able to work upon receiving a SSN either became a permanent resident upon entry (like the spousal visa) or has a complete misunderstanding on what the SSN is. A SSN does not give an immigrant authorization to work.

K3 is dead as designguy already mentioned. But even with K3, you would have to AoS after arrival and wouldn't be able to work right away - you'd have to wait on a EAD as well.
 
CR1 is the only route when married. And also the only route of fiancée / Spouse visa that immediately allows you to work and travel outside of the US.
 
When you enter with a K1, you then get married, apply for AoS together with AP (for travel, as you won't be able to leave the US without AP either - or at least won't get back in once you leave) and EAD. Processing for EAD is around 6 months. So when entering on a K1, expect to not be able to work for at least 6 months after filing the AOS, AP, EAD. 

K3 is dead you wont get one. If you get married CR1 is your only route.
 
EAD takes about 6 months to process depending on your work authorization

We need extra sheets for the address history of the beneficiary. We are calling it I-130A addendum. Beneficiary will sign and date each sheet of the I-130A addendum. Does the Petitioner also need to sign and date each sheet of the I-130A addendum?
