Neha,
Once he files for an I-130 for you, your intentions are clear to the US govt, you are seeking to be an immigrant. However, is there a visa number available for you? As a spouse of a LPR, unfortunately NO. However, there is no need for you to panic, just pray that HIS interview letter comes in the mail very very soon.
If he resides in a district area where an approval of his N400 at the interview is granted, then is sworn in immediately as a citizen, then you will be fine. However, even if he approved and wait for his oath ceremony, you can start working on the completion of the necessary forms to be able to send it out immediately with a cover letter requesting the upgrading of your I-130 petition to an new one, that of an immediate relative. As such, an immigrant visa becomes immediately available for you.
Also, your status has now expired, so don't be frantic and scared. It is part of life and you will be fine once his citizenship is completed. Also, at the interview, they might ask him about his new marriage, which I believe he might have to notify them of his marital status (I may be wrong, but I am 100% sure that, at the oath ceremony, he has to make a note on the form which they send you that you are now married). Also, should the interviewer not ask about his marital status, then HE SHOULD NOT VOLUNTEER HIS LIPS TO THIS FACT. The fact that you are out of status is not going to make him ineligible for US citizenship, the USCIS might be annoyed, but they can't do anything at all.
Lastly, be free to enjoy your husband, go out and have a time of your lifetime. If you let this immigration be a hanging axe over your head, you can easily get depressed. I have seen people in huge distress.... For example, I took my wife to her oath ceremony yesterday, unfortunately a woman attending her swearing in ceremony had a convulsion and fell, since I am not a medical dr, I cannot give you the science of her situation. However, people close to her explain that her immigration journey has been an ardouos one, and she just couldn't believe it will culminate to her being sworn in as a US citizen. Sadly, she wasn't sworn in, she had to go to the hospital for he medical care... so, her immigration journey continues, I personally hope just for a temporary, so she can gain the satisfaction of being a US citizen. My wife told me that she felt really sad for that lady, and so did I.
So, I hope your husband case is adjudicated very very soon, and you are back in the work force.... Also, tell your husband to write a letter every month to wherever he applied for his naturalization, and demand to know why he hasn't been scheduled for an interview. If he waits, he will wait until the Larry King becomes the President of Iceland. Remember that, the bureaucrats at USCIS move when someone's else boot is on their backside....

. So dont you think its better to just wait for a month until my husband gets citizenship. His Fingerprinting is already done in July, so I guess anytime he will be recieving the Interview letter.
