will I lose my chance to a green card?

If the I–130 has not been approved, you will not likely be able to obtain permanent residence through the marriage even though the marriage was bona fide in its inception. Even with an approved I-130 petition, immigration officers will not allow an adjustment of status application to permanent residence continue if the US citizen spouse refuses to continue the case. In the event of separation but no final divorce, there is a possibility of the case continuing if the US citizen spouse consents to its continuation. In the event of a divorce, no continuation of the case would be allowed.  Due to the limitations of the Lawyers.com Forums, Alan Lee, Esq.'s (the "Firm") participation in responding to questions posted herein does not constitute legal advice, nor legal representation of the person or entity posting a question.

You'll have to explain what you mean by your I-130 being in process.  When did you file and what other applications have you filed?
