Dear Afraid,
I would prefer to write in Romanian, will be easier for me.
I don't know about waiver, I am not in the same situation. But everyone tells you to wait for that. You can prepare all the needed papers in case you want AOS. Don't be in hurry with the medicals. Because they cost you and you can do that when you are sure if you want AOS , you have to look in the internet for the list of the doctors in your area and choose one.
In case you want CP you have to ask KCC for that change by e-mail or by phone. Probably you will go in Bucharest for that (I asked for Montreal and not Bucharest because before USA I lived in Canada, and KCC asked me to fax them the proof I lived there, even I put in all the papers I sent them that I am Canadian and I have a valid Canadian passport). I did the mistake and I have all medicals ready made here in USA before I changed my mind, and when I got the second letter with the interview date, I got the list of the recognized doctors, only in Canada. I had to pay again for the medicals, 1100 Canadian dollars (we are 4 people), they took only the vaccines proof, but again bloode and x-rays (in USA if the skin test is OK you don't have to do x-ray).
I saw your number is 4xxx this means you could have the interview in December, if your papers were OK. So you are eligible any time from now to apply for AOS. There are two possibilities, depend what you put in the first set of papers you got at the first letter.
What did you choose there: CP or local USCIS (AOS)?
If you've chosen AOS, just wait for waiver and with all other forms ready, make the medicals in USA, just send them as soon as you are ready and hope everything will be fine for you. If you have chosed AOS and you want CP now, you have to tell KCC when you got the waiver, and ask them to change you for CP in Bucharest. You will need in this case police reports from Romania and other places (if it is your case), but not from USA. You will do the medicals in Bucharest at one of the three centers, this can be done in one day, just before your interview, for this you can read more one the other forum, where you will find more Romanians with all the interview stories.
I don't know your story and why you said your husband to go for CP in Romania, I think you have to go togheter in the same time, is just one interview for the winner and all the other people that follow the winning person in USA.
In which part of USA are you, we can talk if you want, I can phone you, just give me a private message.
