hi guys, I hope you can check out my case and give any tips or guidelines.

me & my sister are planning to renew our US Visas & if possible, apply her almost 2-yr. old daughter for a US Visa too.
me:
28/engaged
officer in a call center, employed for 3.5 years
already got my ITR & COE w/ me
travelled to thailand, china, hk, US
ate:
29/single mom
RN in manila doctors for almost 1 year
travelled to china, hk, US
our previous visas were multiple-entry 10-yr visas. we've both been to the US once (tho not together) & both for vacation purposes. we have 3 aunts in LA, who recently visited manila for a long-awaited family reunion. everybody else in our family (parents, 2 other sisters & brother) still have their valid visas; we just had ours approved at a different date cos we were initially denied but after everyone else had theirs approved, nadaan kami sa drop-box system.

now here are the complications:
my ate is a RN so yun palang feeling ko baka ma-deny na kami agad lol. tbh, when she went to the US before, sinuggest ng titas ko to study nursing so she took it up here as a 2nd course, graduated & passed the board exams but got pregnant so di agad nakapagtrabaho. a lot of people have advised us not to mention her work but wala naman kami mapapakitang ibang ginawa niya as a source of income.. plus she has her daughter (which i don't know if advantage or hindi kasi ties to the phils). one more thing i think pass na siya sa NCLEX (they can prolly confirm this) and so iisipin nila talaga magTNT siya. she is open to working in the US but is currently leaning towards working in Australia, where we have one more aunt. she is not planning on going to the US anytime soon cos bago palang siya sa work niya and may baby pa. a local nurse's salary is not enough for a shopping & tour trip to the US (sadly). she just wants to renew her visa and since sabay naman expiry namin sabay din kami magaapply.
next is me. i will be getting married next year (maganda reason to prove i'm not gonna go TNT). but the thing is US-citizen ang fiance ko and the reason why i need my visa renewed is cos we are open to the option of getting married sa NY. sabi kasi ng friends niya dun it's easier to process the papers kung may tourist visa ako then pakasal kami dun rather than get a fiance visa (tho I can also opt to get this instead). another advantage to this daw is cos if you get the fiance visa we have to get married within 3 months of getting there. if i had a tourist visa, i could get part time work (his dad has a resto there) and earn more money within the 6 months stay so i can get my whole family to go to my wedding (medyo marami din kami all in all 7 people). my fiance grew up and studied here in manila, nagOOC lang sila every year and has stayed in the US for a few years. based on what i've read, i'm pretty sure na di ko to dapat banggitin else madeny yung application ko.
another problem we have is that we don't have a lot of show money. when we get our salary kasi most of the money goes to household expenses and younger siblings' tuition and since my dad had a heart attack, konti nalang income niya from his work.
we were gonna say that the family were supposed to go to the US this summer 2010 but since di pa approve ng doctor yung dad ko for travel, di natuloy. then iusog namin next year on my brother's summer break (May) both as his HS graduation gift & since the other siblings have all gotten stable jobs. but na-expire nga visa namin so we need to renew. we're also encouraging another tita & her son to apply with us para mas convincing cos we know our chances our (very) slim.
may possibility naman talaga na magbakasyon kami sa US lahat next year, but mas malaki
[textspeak!] chance na mauna ko and then they go to the US at a later date for my wedding.

please help. any advice will be greatly appreciated.

(and terribly sorry for my long post)
