i see you

First thing, Hepatitis is not a genetic disease. Hepatitis B is caused by a virus and can be spread through blood, sex. Who diagnosed you as having hepatitis B? Did your doctor checked your hepatitis profile (quantitative and not just qualitative test)? If you have Hepatitis B Ab (antibodies) then that means you've been exposed to someone who had hepatitis B or your mother had hepatitis B and passed it on to you (transplacental). But if you are Hepatits B Ag positive (HBsAg), then you have the disease and is therefore can be transmitted to your partner. Your Doctor will have to determine also the other types of Hepatitis A, C, D, E, etc... and your ALT and AST level, because only through this that your Doctor can determine if you will need treatment and candidate for the anti-viral medicine (to slow down the replication of the virus and possibly seroconvert you), or if you will be needing Interferon. Problem with Chronic Hepatitis B is the possibility of having Liver Cancer. I am not trying to scare you, but you do need to be checked and have your doctor make you a medical certification, stating the type of hepatits you have and treatment that he/she will be giving you.
In Reference from the TECHNICAL INSTRUCTIONS FOR MEDICAL EXAMINATIONS:
Communicable Diseases of Public Health Significance
active tuberculosis, human immunodeficiency virus (HIV) infection, infectious syphilis, chancroid, gonorrhea, granuloma inguinale, lymphogranuloma venereum, and Hansen's disease (leprosy)). Applicants with any of these diseases were excludable. The new law refers to these as "communicable diseases of public health significance." Hepatitis is not included, so you can relax. They only require applicants to have Vaccinations for Hepatitis, but in your case, if you have the antibodies and the qualitative results is already high, then you don't need to have the vaccine. There is one Filipino applicant who is also hepatitis B positive and he only showed the Panel Physician a copy of his medical certificate (diagnosis and treatment) and he passed his medical exam. So don't worry too much. Good Luck and God Bless.

Marriage must be founded with pure understanding... It's not about how grand the wedding is but how you keep the marriage works. If he can't seem to afford a big wedding for now then you must understand him... Again it's not about being big and opulent but how you'll keep it sacred... Sometimes we must learn how to appreciate simple joys and blessings to see how true happiness really means Good luck and all the best to both of you <3

I know how you feel. I wanted a nice wedding too, so I really planned it. I think what you can do is do some research on your area, and already find a dress there. If you present to him all the details, cost, and have it all planned out already and tell him everything in exact terms, maybe he would consider it. The key here is to be proactive, and also to know your limits. When I planned my wedding, I covered all bases, he did not have to do anything but show up! I was also upfront about all expenses, and I already knew how we would pay for it. I know it seems hard, but if you really want it, you can do your own research, maybe he is worried about expenses and having to plan it. All I know is you can have a beautiful civil wedding, or a garden wedding in someone's home for a couple of hundred dollars. You just need to be creative. Tell him how you feel, and also ask his reasons why he wants it right away. Maybe it's a religious thing, like not wanting to live together without being married? Lastly, like others said, you can always get married twice, but to me, I did not like that idea. I wanted one special day, and for that to be it. If that is what you want too, talk to him. After all, it is your special day!

being a man myself i understand him wanting to keep it simple... but being a man i also understand that eventually, what my fiancee wants my fiancee gets lol. just gotta keep nagging at him lol
have a wedding that you can afford but compromise... keep it relatively simple but have it well organised and beautiful

well maybe he was thinking bout money,remember bringing you in states is kinda expensive somehow you have to understand him for that matter.no matter how we wanted to have nice wedding if hindi naman kaya ng budget we should settled nalang muna kung ano kaya ng hubby mo..pero tell him kung ano nararamdaman mo bout it.pero kung mag share ka sa wedding pwedi mo din suggest sa kanya yun..

Yeah, that's tough, that's guilt tripping right there. I can get she'd want the support, but reassure her that the interview will go okay - and call you before and after she goes in to at least offer something for support. The process is stressful (and maybe she hasn't seen you in person in awhile?) so check into what else could help her out for the interview, maybe her bringing a family member or friend?
You could also go into your schedule too (along with money expenses on how much money comes in and out). My fiance probably won't be at my interview because taking time off work = more money lost.
And I guess you could also point out theres high cost in paying for the blasted K-1 visa process, then have to pay for moving, then have to keep money saved for wedding, honeymoon, and money to keep you both afloat until she is able to work.

Like you say, she probably doesn't understand how bills work. Heck, before I had a car I had no idea how much running and maintaining a car cost! Similarly, tuition and textbook costs are far, far higher in the US than in most other countries.
Can you give her some hard numbers? Perhaps list all of your monthly expenses in a spreadsheet to show your outgoings? Perhaps you could even scan a receipt or two.
