Dear Sir or Madam,
I think that you've posted this question in the wrong forum. This is an immigration law forum, and "removal" in the immigration context is something entirely different. You should see if AVVO has a section on landlord tenant law.
I agree with the other attorneys who have commented on this matter - namely that the best interest of the child standard will be applied and that immigration status alone should not have significant influence on what the court determines is in the children's best interests here. I would add, however, that I would hope that the mother involved in this matter has a skilled family law attorney helping her in family court.
This is an incredibly broad question, and as a preliminary matter if you're asking it, I think that you or someone you know needs to consult with an experienced immigration attorney very soon. Since you have not provided more details about a specific concern, I think it is safe to say that there are three main ways in which a person's permanent residence can be in jeopardy after adjustment of status:
1) Being convicted of certain crimes;
2) Having USCIS or another law enforcement agency...
I agree with Attorney Behar, but would add that if you travel internationally after April 2014, you would need to appear at a US consulate for visa stamping in order to reenter the United States. The I-94 controls your ability to live and work within the United States, and a visa is like an invitation to come to the United States and ask for an I-94 at the airport, land border, etc.
I agree with Attorney Segal. These are deceptively tricky cases. There's a lot on the line here and I think you owe it to yourself and your family members to speak with an attorney, maybe even several, to find an ally to take with you to the interview/conference.
You are generally correct about the process - PERM, I-140, I-485. You can track PERM processing times through the Department of Labor's iCERT web site: http://icert.doleta.gov/. Right now they report that they're processing PERMs filed on or around September 5, 2012 - so there's a roughly eight week processing time for the PERM.
With respect to the next step, a lot depends on how long it takes for the I-140 to be approved and what USCIS Service Center it will be filed...
I think you need to speak with an immigration attorney. If you entered at a regular port of entry as a Canadian, it means that you were likely inspected and admitted. If this is the case, and you are married to a United States citizen, then I am unsure why you're trying to use 245i to adjust to permanent resident status. You may want to check with an immigration lawyer to make sure you've applied using the right forms and processes.
This is a delicate, but not uncommon issue. I highly recommend that you consult with an immigration attorney to discuss this matter because there may be several steps involved in a case like yours. Since you are still married, you have to answer "yes" to the question about your marital status. And since you're still married, you cannot opt out of the joint-filing requirement. What may end up happening is that you file the I-751 jointly now - to avoid termination of your CPR status - and...
Good morning. This is definitely a situation where I think that you and your employer would be well advised to consult with, and likely work with, an immigration lawyer. An H1b transfer might work, it just depends on what the requirements for the job are in terms of experience and education required for the job. An h2b is perhaps not a great choice because it they only allow a person to work in the US for a season, meaning that part of the year you'd have to leave the US. And E visas have a few...
