Petitioner Enrique Valentin Oviedo Meli-an appeals from a decision of the Board of Immigration Appeals (BIA) upholding an immigration judge’s order that he be deported. We affirm the judgment of the BIA.
I.
Petitioner is a citizen of the Dominican Republic. He entered the United States on October 22, 1978, on a “B-2” visa as a temporary visitor for pleasure. See 22 C.F.R. § 41.12 (1978). He did not become a permanent resident of the United States, or immigrant, until June 24, 1982. 1
In 1986, petitioner was convicted of possession with intent to distribute cocaine in violation of 21 U.S.C. § 841(a)(1) (1982) (currently codified at 21 U.S.C. § 841(a)(1) (1988)), and placed on probation. Because an alien who commits a controlled substance offense while in the United States may be deported, 8 U.S.C. § 1251(a)(ll) (1982) (codified as amended at 8 U.S.C. § 1251(a)(2)(B) (1988 Supp. Ill 1991)), on May 28, 1987, the Immigration and Naturalization Service (INS) initiated deportation proceedings against petitioner by issuing an order for him to show cause why he should not be deported (Show Cause Order). An immigration judge subsequently found petitioner to be deportable. The BIA issued its final determination affirming the immigration judge’s order on November 21, 1990.
Petitioner concedes on appeal that his criminal conviction renders him deportable under 8 U.S.C. § 1251(a)(ll). He seeks, therefore, a discretionary waiver of deportation pursuant to section 212(c) of the Immigration and Nationality Act, 8 U.S.C. § 1182(c) (1988). Section 212(c) vests in the Attorney General the discretion to admit into the United States “[ajliens lawfully admitted for permanent residence” who seek to return from abroad, if the United States previously had been their “lawful unrelinquished domicile of seven consecutive years.”

Although by its terms this statute pertains only to aliens seeking to reenter the country, it has been interpreted as also authorizing relief from deportation for aliens who lawfully have been domiciled in the United States for at least seven consecutive years.
See, e.g., Tapia-Acuna v. INS,
II.
Whether petitioner is eligible for section 212(c) relief depends on what triggers and what terminates “lawful domicile.” The INS argues that petitioner’s lawful domicile commenced on June 24, 1982, when he obtained permanent resident status, and ended on May 28, 1987, when it issued to petitioner the Show Cause Order. If the INS is correct as to both dates, then petitioner was lawfully domiciled in the United States for less than five years and is not *1524 eligible for relief under section 212(c). Petitioner argues that his lawful domicile began on October 22, 1978, when he entered the United States, and did not end until November 21, 1990, when the BIA issued its final determination of deportation. If petitioner is correct as to either date, then he was lawfully domiciled in the United States for more than seven consecutive years, and is eligible for discretionary relief from the Attorney General. 5
A.
The Immigration and Nationality Act does not define “lawful domicile.” “Domicile” is, however, a concept widely used in other areas of law.
Mississippi Band of Choctaw Indians v. Holyfield,
Nothing in the Immigration and Nationality Act suggests that Congress intended to depart from this time-tested definition when it enacted section 212(c). To the contrary, requiring an alien seeking extraordinary relief from deportation to establish sustained, continuous, and lawful physical presence and intent to remain in this country is perfectly consistent with the purpose of section 212(c): to provide an opportunity for relief from the harsh sanction of deportation for those aliens who are likely to have developed strong ties to this country.
See, e.g.,
S.Rep. No. 1515, 81st Cong., 2d Sess. 383 (1950); S.Rep. No. 355, 63d Cong., 2d Sess. 6 (1914) (“[I]t seems only just and humane ... to permit the readmission to the United States of aliens who have lived here for a long time and whose exclusion ... would result in peculiar or unusual hardship.”);
Castillo-Felix v. INS,
We say that lawful domicile means “at least” this because some courts and the BIA have held that lawful domicile does not begin until the alien obtains permanent resident status, regardless whether at some earlier time he established a lawful intent to remain indefinitely in the country.
See Michelson v. INS,
Petitioner established a lawful physical presence in the United States on October 22, 1978, when he entered the country on a proper B-2 visa. He did not establish a
lawful
intent to remain in the country indefinitely, however, until he was granted permanent resident status. For an alien’s domicile to be considered “lawful,” he must at least comply with this country’s immigration laws.
Lok III,
Because petitioner entered the United States in October 1978 on a B-2 visa, his lawful domicile did not commence at that time. He has not shown that his legal status changed prior to his becoming a permanent resident in June 1982 so as to render lawful his intent to remain in the United States. 7 We conclude, therefore, that the Board of Immigration Appeals correctly held that petitioner’s lawful domicile began on June 24, 1982.
B.
The immigration judge held that petitioner’s lawful domicile terminated on
*1526
May 28, 1987, when the INS issued the Show Cause Order in this case.
See Ballbe v. INS,
III.
Petitioner’s lawful domicile commenced on June 24, 1982, and terminated on May 28, 1987. Accordingly, petitioner is ineligible for discretionary relief from deportation under section 212(c).
The decision of the Board of Immigration Appeals is AFFIRMED.
Notes
. Petitioner was granted immigrant status as the unmarried son of a lawful resident alien. See 8 U.S.C. § 1153(a). He is now married to an American-born wife, and their child is American-born as well.
. The section provides in relevant part:
Aliens lawfully admitted for permanent residence who temporarily proceeded abroad voluntarily and not under an order of deportation, and who are returning to a lawful unre-linquished domicile of seven consecutive years, may be admitted in the discretion of the Attorney General....
8 U.S.C. § 1182(c).
. In
Bonner v. City of Prichard,
. In effect, petitioner seeks from us only temporary relief from deportation. Even if we were to grant him relief today, he still would not be guaranteed an ultimate waiver of deportation under section 212(c).
. If petitioner’s lawful domicile commenced on October 22, 1978, then even if it terminated when the Show Cause Order was issued on May 28, 1987, he was lawfully domiciled for more than eight and a half consecutive years. Similarly, if petitioner's lawful domicile terminated on November 21, 1990, then even if it did not begin until he became a permanent resident on June 24, 1982, he was lawfully domiciled for just under eight and a half consecutive years.
. The INS urges us to adopt the more restrictive position in this case. We recognize that an interpretation by the administrative agency charged with implementing a statute is entitled to deference.
See, e.g., Caro-Galvan v. Curtis Richardson, Inc.,
In
Elkins v. Moreno,
. It is undisputed that an alien who has obtained immigrant status may lawfully intend to remain in this country.
