what are the consequences if I failed to file I-751( to remove conditional status on green card)before 90days?

Answer 1

Failure to file within the 90 days will automatically terminate your status and you will be subject to deportation from the US.

From USCIS's website:

During the 90 days before the second anniversary of the date you obtained conditional resident status you and your spouse (if still married) must file to remove the condition. You must file a Form I-751 (Petition to Remove the Conditions on Residence). All petitions should be sent to the Service Center that serves the area where you live. Failure to file will result in loss of your resident status. Late filings are permitted with sufficient explanation of the reason(s) for being late in filing.

Evidence that the termination of your conditional resident status and your removal from the country will cause you extreme hardship, includes but is not limited to the following:
- USCIS Form I-751 (Petition to Remove the Conditions on Residence)
- Copy of USCIS Form I-551 (Permanent Resident Card)
- Evidence that your deportation would cause greater hardship than the hardships created when other aliens are removed from the United States.

However you should note that in evaluating the claim that your removal from the United States will cause you extreme hardship, the Service will only consider factors which arose after the date you obtained your conditional permanent residence.

Answer 2

That depends on how bit of an ****** U.S Customs decides to be. There can be a fine up to 1,000 dollars per person.

That's why you're supposed turn in your green card to the ticket agent as you're checking in. Then the agent would turn it in to the CBP offices and you wouldn't have to worry about it anymore. However, this happens all the time so it might be a really long time before they get to you...but sooner or later, they will. This is what happens when you fly. I don't know if procedure changes when you drive from country to country

Answer 3

I DO NOT KNOW BUT IF I WERE YOU I WOULD "NOT" PUT IT TO THE TEST.
