Civil court judgements against an individual will not endanger a permanent resident's status. However, criminal court proceedings (both in the US and a person's home country) have to potential to affect a person's US Immigration status. The status of your child custody arrangement will have an impact on US immigration's viewpoint, too. While Family Court is usually a civil concern, it can have criminal overtones, too, particularly if you are seriously in arrears and have had a bench warrant issued for failure to pay.
You should talk to an immigration lawyer in the US, and possibly have them speak to a Family Law attorney in Canada, as the exact nature of your situation will undoubtably be complex, and there is no good general answer that can be given here.
yes
If it's an American Green Card then no you can't. You must go through the appropriate channels to immigrate to Canada. If it's a Green Card of Canada (which is actually called a Permanent Residency Card in Canada) then yes you can live in Canada.
Can I get a Twic card owing back child support
yes they can do that
They would get prosecuted in the 1st instance and run the risk of deportation and would at the minimum struggle to get the Green Card renewed and also be unlikely to be able to apply for citizenship
You would need to work with the Philippines child support agency to accomplish this.
Any child of a green card holder is eligible to apply, married or not. But the wait time for married children and children over the age of 18 is about 10 yrs.
Pay your child support.
No. The child is considered a US citizen being born there and does not require a green card. The parents can apply to become citizens but they have to already have a green card. Every body is entitled to get a green card and apply for citizenship .
You need to go to the agency in charge of child support enforcement in your area of residence and file for child support, or engage the services of an attorney experienced in international family law to do the same. They will take it from there.
If you are a dependent (are not her adult child) and she has applied for your green card same time as hers.
No there is no benefit of green card after 12th class
