The Green Card you received is the permission to live and work in the United States. Many people look with anticipation to the day they receive their Green Card (I did). You got your Green Card and only a month later left the U.S. again. You had a good reason (your daughter and grandfather), but you were outside the U.S. four times longer than you were inside, and CBP does not like that at all.
There is no firm rule for how often and how long you can be outside the U.S, aside from the absolute maximum. It helps to apply common sense. If CBP feels that you are not really residing in the U.S. they can pull the plug on you at any time. Now you are mentioning that you are planing on leaving again. See, most people have to work for a living. Thus, they cannot afford vacations that take four months, come back for a bit, and then leave again. Those who do not work are usually married, and it's also not "normal" that one spouse lives in the U.S., while the other one spends most of her time in a foreign country. You can't really blame CBP for giving you a formal warning. You should be grateful for this.
Since it's possible that CBP made an entry in your A-file, I would suggest for you to take the residency requirement serious. Reside in the U.S., permanently, take one or two vacations per year, but not vacations that take several months, if you don't want to risk losing your Green Card.

Either way Bin Laden is dead. The best part is he got to ####### his pants when he realized it was up.

There were about 3,000 people killed on 9/11 who were unarmed.
Don't really care if OBL was armed or not; don't care if he was firing back or not.
I just care that he's dead.

I'm very very happy, finally. I know this will not bring back those who lost their lives, but, justice has finally happened, and those who died can now rest in peace.

Checking 'no' is not okay if you wish to gain US citizenship. You need to check yes. If you don't you will not be granted US citizenship.
The important thing to remember is that the US does not officially recognize dual citizenship so you are not applying for dual citizenship. You are applying for US citizenship only. Once granted, the US will recognize you as a US citizen only.
The other important piece of information, however, is that Canada does not recognize the US Oath of citizenship as renouncing Canadian citizenship. Canada does officially recognize dual - or more - citizenship, so once you accept American citizenship, to Canada you are both a Canadian and an American citizen. The only way to renounce your Canadian citizenship in a way that Canada recognizes is to file an official Canadian immigration document renouncing your Canadian citizenship with CIC and having them approve it. Without taking that step, no oath in any other country no matter what the words, will stop you from being a Canadian. Only Canada is able to grant you Canadian citizenship and only Canada is able to remove it. The US can't, however, they do ask that anyone applying for US citizenship take the oath renouncing former allegiances in the view that you cannot serve 2 masters.
The choice is, ultimately, your own. This is something many Canadians have had to deal with, including me. I disliked some of the words of the US Oath of Allegiance - not because I was any less committed to fulfilling my obligations as a US citizen - but because I do not see a conflict in having citizenship in both countries. I am choosing to add the US citizenship to who I am, not taking away my Canadian citizenship from who I am. This, in its very essence, defines the major difference between the two countries: for the US everything is black and white - either/or - for us or agin' us, win-lose; in Canada we understand that there are varying degrees of gray, that you give a little and take a little, and that things don't have to be win-lose - they can be win-win instead.
If you want US citizenship you need to answer yes to that question. Only you can decide if you are able to honour two masters - the US and Canada.

Sorry you are home sick. That must be really hard.
You are the same age as me and I can see a lot of your feelings are one's I've also had briefly.
My best best advice (feel free to say, no thanks!) Is suck it up. Have fun. If you really hate it, you and your husband can move, but until the time comes when you can do that, have fun! This can all be some crazy story you tell your kids about. We all want to live independently and have great jobs, especially at our age when you've spent all that time in school and perhaps even had a taste of a good job with good money! It will come...now is the time to live in one room and save as much as you can, I know you yearn for a different lifestyle but you will get there...at 27 we are in the 'building stage' of life. Please try to have fun and enjoy the adventure. I have no experience of the cultural issues you may be dealing with (I live in Vermont). If I were you I'd be getting any old job (retail or otherwise) and showing people that you are the type of woman who takes care of business. You can work your butt off to make ends meet and you'll have fun doing it...because YOU KNOW it's only temporary! You may be feeling oppressed and downtrodden by the role of women where you live...I hope you find a way to get out there and be a role model. You are obviously intelligent, educated and adventurous. I am also sure there are other intelligent women for you to talk to there...can you check out groups at the local library, online meet up sites, put up posters for a 'womens only' book group or something? I met a lot of nice people here in Vermont by turning up at local yoga classes and volunteering. I haven't made any real friends yet but I am having fun and my first invitation to a social event, that wasn't because I was a +1 with my husband, was from my 65 year old yoga teacher...I was very proud of that.
Hang in there...it is hard, you are right. Especially to go from being self sufficient to finding yourself in the role of 'housewife' with no friends. (I was there too) Don't lose yourself in your surroundings and your situation. This too shall pass.

yes i realize that, i never mentioned i was applying for dual citizenship, just that i wanted to retain my CND and become a dual citizen.
And thanks for the link! Exactly the type of article i was looking for!
perfect, thank you! I didnt realize you had to pay to renounce. Silly me and taking the words id have to say for what they sounded like they meant!
