Defendant Jesse Gary Soliz appeals from his conviction on two counts of transporting illegal aliens in violation of 8 U.S.C. § 1324(a)(1)(A)(ii). He contends that the district court erred in denying his motions to suppress and for acquittal because the Border Patrol Agents conducted a warrantless search in violation of his Fourth Amendment rights. He also contends that the district court erred in denying his motion to suppress his sworn statement because it was taken in violation of his Fifth Amendment privilege against self-incrimination. The district court had jurisdiction pursuant to 18 U.S.C. § 3231. We have jurisdiction pursuant to 28 U.S.C. § 1291. We affirm in part and reverse in part.
BACKGROUND
The Border Patrol received reports of alien smuggling activity afoot at Apartment 4, 3142 National Avenue, in San Diego. Consequently, a group of six or seven agents^ led by Agent Michael Bliven, went to the premises to investigate these reports.
3142 National Avenue is a rectangular lot with a two-story building in front and a one-story duplex in the back. Apartments 1 and 2 are located in the front building and Apartments 3 and 4 are located in the back duplex. Behind units 1 and 2 and across from units 3 and 4, there is an open gravel parking area which is accessible from a driveway gate, off of a public alley, at the back of the complex. From the alley, which is parallel to National Avenue, one is able clearly to see the parking area through a chain link fence which surrounds the entire property. The premises can also be accessed through a walk-in gate on National Avenue. On the day of the arrest, that gate was broken off and laying on the side of the fence. A walkway leads from the gate to the front of the two-story building and continues around to the back of the premises. There were no “No trespassing” signs on the property.
Upon arriving at the premises, two agents went to secure the alley while two others proceeded to the front door of the two-story building. Agent Bliven made his way to the rear of the property and, as he did so, he saw two cars parked in the gravel area. Agent Bliven observed Soliz standing behind one of the cars over its open trunk which contained three persons inside. Soliz saw Agent Bliven and started to close the trunk. Agent Bliven identified himself as “Border Patrol” and instructed Soliz to stop. After speaking with the persons in the trunk, Agent Bliven determined that they were Mexican nationals illegally in the United States and placed Soliz under arrest. At this time, several illegal aliens were caught attempting to flee from Apartment 4.
While in custody, Soliz was asked if he wanted to make a sworn statement regarding his true citizenship and nationality and his activity at the house. Soliz responded affirmatively. Thereafter, he was advised of his Miranda rights and was again asked if he were willing to make a statement. Soliz replied, “Yes, regarding my eiti-citizenship.” The questioning then proceeded as follows:
Agent: Your [sic] also being investigated concerning ... smuggling activity in the house by which you were arrested, you understand?
You understand that we’re also gonna be asking questions about ... your activities.
Soliz: I thought this was just about my citizenship.
Agent: As initially stated in the — uh— beginning of the tape, I asked that we were gonna talk to your [sic] about you [sic] citizenship and the activities at the house in which you were arrested, okay, you said you would talk about your citizenship but I’m also asking you about the activities at the house sir.
Soliz: I don’t know about these activities at the house.
Agent: Okay. According to our observations and also the material witnesses we have.
Soliz: I was sent there.
Soliz then proceeded to make admissions regarding his role in transporting illegal aliens.
*502 Soliz moved to suppress his post-Miranda statements. Finding that Soliz had knowingly waived his Miranda rights, the district court denied the motion. Soliz also moved to suppress the evidence found at 3142 National Avenue, on the ground that the warrantless search violated the Fourth Amendment. The district court concluded that since there was no “surreptitious violation of the curti-lage,” Soliz’s Fourth Amendment rights were not violated by the Border Patrol Agents. Soliz timely appealed from his conviction.-
DISCUSSION
A. Determination of Curtilage
Whether an area is within the protected curtilage of a home is an essentially factual inquiry.
United States v. Depew,
The Fourth Amendment protects the curtilage of a home, and the extent of the curtilage is determined by whether the individual may reasonably expect that the area in question should be treated as the home' itself.
United States v. Dunn,
To aid in this inquiry, the Supreme Court has developed a four-factor test. The court must consider: (a) the proximity of the area claimed to be curtilage to the home; (b) whether the area is included within an enclosure surrounding the home; (c) the nature of the uses to which the area is put; and (d) the steps taken by the resident to protect the area from observation by people passing by.
Dunn,
First (proximity):
The parking area was adjacent to the residence, although the record does not reveal the distance between the parked cars and the apartment units. Our cases are not consistent as to the distance required for a finding of curtilage.
Compare Dunn,
Second (enclosure):
A fence surrounded the entire property. However, it was a chain link fence through which the public could easily see — -it was not intended to shield the property from public view. The mere existence of such a fence does not necessarily demonstrate enclosure of curtilage.
See United States v. Van Damme,
Third (use):
The use factor is helpful in determining whether the parking lot was an area which contained activities associated with the “sanctity of a man’s home and the privacies of life.”
Oliver,
Fourth (steps taken to prevent observation):
No steps were taken here to prevent outside observation of the parking area. The fence surrounding the property did not prevent people from peering in, the gate was strewn on the ground, and the property could be viewed from both the street and the alley.
See Traynor,
Analysis of the four factors supports the district court’s finding that there was no violation of the curtilage in this case. The first and second factors could support a finding of curtilage. However, the third and fourth factors strongly militate against such a finding. We conclude that the parking area in which Agent Bliven found Soliz was not “so intimately tied to the home itself’ to be “placed under the home’s ‘umbrella’ of Fourth Amendment protection.”
Dunn,
B. Selective Waiver of Miranda Rights
Soliz argues that the district court erred in denying his motion to exclude his sworn statement regarding his activities at 3142 National Avenue because it was taken in violation of his Fifth Amendment privilege against self-incrimination. Soliz claims that he selectively waived his Miranda rights only regarding his citizenship and that his other statements regarding his activities at 3142 National Avenue were obtained in violation of his privilege against self-incrimination.
We review de novo the district court’s decision to admit the statement.
Smith v. Endell,
A defendant may . selectively waive his
Miranda
rights by agreeing to answer some questions but not others.
Michigan v. Mosley,
Here, Soliz responded affirmatively when asked whether he desired to have his sworn statement taken regarding his true citizenship and nationality and his activity at the house. 2 Then the Agent Mirandized Soliz. At the conclusion of the Miranda warnings, the Agent again asked Soliz if he were willing to make a statement. Soliz then replied, “Yes, regarding my ... citizenship.” We find that this statement constituted an unequivocal invocation of Soliz’s right to remain silent on all issues, except his citizenship. 3
A person in custody may selectively waive his right to remain silent by indicating that he will respond to some questions, but not to others.
Lopez-Diaz,
After Soliz invoked his right to remain silent on all subjects, except his citizenship, the agent violated his right by proceeding to question him about other activities. “Once a person has indicated that he does not wish to talk about a particular subject, all questioning must cease.”
Id.
at 664 n. 2. A statement obtained after the invocation of the right to remain silent is admissible only where the individual’s “right to cut off questioning” has been “scrupulously honored.”
Id.
at 664 (citing
Mosley,
AFFIRMED in part, REVERSED in part, and REMANDED for a new trial.
Notes
. Because we affirm the district court's no-curti-lage finding, we do not reach the government's challenge to Soliz's standing to assert a Fourth Amendment claim.
. This fact was in dispute at the suppression hearing. However, the district court credited the government's version of events. We accept this finding as not clearly erroneous.

violations may be subject to harmless error review,
