The immigration laws provide for the automatic conversion of the family based immigrant classification of the beneficiary of an approved petition in most cases where the petition or beneficiary's status changes (such as by age, marital status, or citizenship). The applicable regulation provides as follows:

8 CFR 204.2(i)(1)(i)Automatic conversion of preference classification.

204.2(i)

(1) By change in beneficiary's marital status.

(i)  A currently valid petition previously approved to classify the beneficiary as the unmarried son or daughter of a United States citizen under section 203(a)(1) of the Act shall be regarded as having been approved for preference status under section 203(a)(3) of the Act as of the date the beneficiary marries. The beneficiary's priority date is the same as the date the petition for classification under section 203(a)(1) of the Act was properly filed.

(ii) A currently valid petition previously approved to classify a child of a United States citizen as an immediate relative under section 201(b) of the Act shall be regarded as having been approved for preference status under section 203(a)(3) of the Act as of the date the beneficiary marries. The beneficiary's priority date is the same as the date the petition for 201(b) classification was properly filed.

(iii)  A currently valid petition classifying the married son or married daughter of a United States citizen for preference status under section 203(a)(3) of the Act shall, upon legal termination of the beneficiary's marriage, be regarded as having been approved under section 203(a)(1) of the Act if the beneficiary is over twenty-one years of age. The beneficiary's priority date is the same as the date the petition for classification under section 203(a)(3) of the Act was properly filed. If the beneficiary is under twenty-one years of age, the petition shall be regarded as having been approved for classification as an immediate relative under section 201(b) of the Act as of the date the petition for classification under section 203(a)(3) of the Act was properly filed.

(2) By the beneficiary's attainment of the age of twenty-one years.

A currently valid petition classifying the child of a United States citizen as an immediate relative under section 201(b) of the Act shall be regarded as having been approved for preference status under section 203(a)(1) of the Act as of the beneficiary's twenty- first birthday. The beneficiary's priority date is the same as the date the petition for section 201(b) classification was filed.

(3) By the petitioner's naturalization.

Effective upon the date of naturalization of a petitioner who had been lawfully admitted for permanent residence, a currently valid petition according preference status under section 203(a)(2) of the Act to the petitioner's spouse and unmarried children under twenty-one years of age shall be regarded as having been approved for immediate relative status under section 201(b) of the Act. Similarly, a currently valid petition according preference status under section 203(a)(2) of the Act for the unmarried son or daughter over twenty-one years of age shall be regarded as having been approved under section 203(a)(1) of the Act. In any case of conversion to classification under section 203(a)(1) of the Act, the beneficiary's priority date is the same as the date the petition for classification under section 203(a)(2) of the Act was properly filed. A self-petition filed under section 204(a)(1)(B)(ii) or 204(a)(1)(B)(iii) of the Act based on the relationship to an abusive lawful permanent resident of the United States for classification under section 203(a)(2) of the Act will not be affected by the abuser's naturalization and will not be automatically converted to a petition for immediate relative classification.
