1. The Border Patrol sets out to protect U.S. borders by simultaneously focusing on five key strategies: apprehending terrorists and terrorist weapons illegally entering the United States; deterring illegal entries through improved enforcement; detecting, apprehending, and deterring smugglers of humans, drugs, and other contraband; using 'smart border' technology; and reducing crime in border communities, thereby improving quality of life. Agents are trained to understand each of these areas, and need to be ready on short notice to implement any or all of these strategies.From the information given above, it can be validly concluded that Border Patrol Agents

2. A-1 and A-2 visas to the United States are valid for as long as the Secretary of State extends recognition to the holder. A-3 visas are valid for not more than three years but may be extended in increments of not more than two years. In 2014, A-1 visas are given to Adara Janus, her husband, and their two children, because Adara is an ambassador from her country. At the same time, an A-3 visa is given to Oden Wolf, Adara's personal assistant. Also in 2014, an A-2 visa is given to Hedrick Yuli, an employee of his country's government, and an A-3 visa is given to Ron Tripp, Hedrick's personal secretary.From the information given above, it can be validly concluded that, if Hedrick asks Ron Tripp to remain in the United States for nine years, until the year 2023, Ron

3. Grounds for deportation of aliens fall into two broad categories. The first covers prohibited acts committed at or prior to entry into the United States (which includes having entered the country illegally—for example, by falsifying documents or evading inspection at the ­border). The second covers prohibited acts committed since entry into the United States (for example, committing a criminal offense or engaging in activity whose purpose is the overthrow of the U.S. government by force). In regard to the former category, the Immigration and Nationality Act permits the Department of Homeland Security (DHS) to look back and deport aliens who should not have been admitted in the first place, had their prohibited acts been known.

4. A U.S. citizen can lose his or her citizenship in one of two ways, by denaturalization (which applies to naturalized citizens only) or by expatriation (which can apply to both naturalized citizens and citizens by birth). Denaturalization takes place when a court revokes the naturalization order because it is found to have been illegally or fraudulently obtained. Expatriation takes place when any citizen voluntarily abandons his or her country and becomes a citizen or subject of another. The Supreme Court has said, however, that the expatriate must have voluntarily performed an expatriating act in order for loss of citizenship to occur (examples are becoming a citizen of another country, serving in the military of a hostile country, or formally renunouncing nationality before a diplomatic officer of the United States).

5. The U.S. Supreme Court has consistently held that the decision to admit an alien to the United States or to exclude an alien from the United States lies entirely with Congress and that Congress can set whatever terms it chooses. Congress has the authority to discriminate on the basis of nationality, race, political belief, moral character, or mental or physical disability. In addition, Congress can grant special preference to relatives of U.S. residents, and to persons possessing work skills that would tend to boost the U.S. economy. However, once admitted to the United States, aliens can claim most of the protections guaranteed by the Constitution—for example, freedom of speech and religion, freedom from unreasonable search and seizure—but not the right to hold federal elective office. Persons who are undergoing proceedings to expel them from the United States are likewise granted the safeguards of due process under the Fifth Amendment and cannot be compelled to incriminate themselves.From the information given above, it CANNOT be validly concluded that

6. The Immigration and Nationality Act (INA) provides for naturalization, the process by which a foreign citizen or national can become a U.S. citizen. Some of the requirements are continuous residence and physical presence in the United States; an ability to read, write, and speak English; a knowledge and understanding of U.S. history and government; and favorable disposition toward the United States.

7. Immigrants may try to enter the United States illegally for a variety of reasons. Among these reasons are to get jobs they hope will improve their financial situation, to reunite with family members in the United States, and to find political freedom. There's ongoing debate in the United States about how many immigrants should be admitted and under what conditions. Meanwhile, smugglers known as coyotes take advantage of the situation by collecting thousands of dollars from those wishing to cross the border illegally. For their money, immigrants often endure days or even weeks of unpleasant conditions and no guarantees of success or even survival.

8. Border Patrol Agents are sometimes required to testify in court about their activities leading up to and during an arrest. Therefore, agents must have excellent communication skills. They need to be able to express themselves clearly in court and elsewhere so they are understood without confusion or misinterpretation. By their choice of words and how they speak, they must demonstrate to a judge or jury that they are confident and capable. A public speaking course would be an excellent way for agents to ensure that they're making the best possible impression in court.

9. Law enforcement agencies use scientific techniques to identify suspects or to establish guilt. One obvious application of such techniques is the examination of a crime scene. Some substances found at a crime scene yield valuable clues under microscopic examination. Clothing fibers, dirt particles, and even pollen grains may reveal important information to the careful investigator. Nothing can be overlooked, because all substances found at a crime scene are potential sources of ­evidence.

10. The printed output of some ­computer-­driven printers can be recognized by forensic analysts. The Acme Model 200 printer was manufactured using two different inking mechanisms, one of which yields a Type A micro pattern of ink spray around its characters. Of all Acme Model 200 printers, 70% produce this Type A micro pattern, which is also characteristic of some models of other printers. Forensic analysts at a crime lab have been examining a falsified document that clearly exhibits the Type A micro ­pattern.From the information given above, it can be validly concluded that this document

11. Visa regulations allow employers in certain industries to hire foreign nationals for seasonal positions. These employers must first try to hire U.S. workers for these positions. Eligible industries include landscaping, seasonal hospitality and seasonal construction, and certain jobs in manufacturing, food packaging and processing, fisheries, and retail. Agriculture is not an eligible industry. Workers must return to their home countries at the end of the season. The program benefits both employers who need workers and foreigners who need the income.

12. One way that a foreign national is eligible to become a lawful permanent resident of the United States is by being sponsored by a relative. The relative must be able to prove that he or she is a citizen of the United States and must demonstrate that he or she can support the foreign national at 125% above the mandated poverty line. In addition, if the relative is a U.S. citizen, then he or she may sponsor a husband or wife, unmarried children under 21, married son or daughter of any age, brother or sister (if the sponsor is at least 21), or parent (if the sponsor is at least 21).

13. Although undercover work by the police or by government officials is allowed, it has limitations. For example, if an officer or agent of the government induces a person to commit a crime that the person has not contemplated committing, for the purpose of instituting criminal prosecution against that person, this is called entrapment and is illegal. Entrapment can occur in two ways: (1) by knowingly representing the crime in a false light, so that it will not be seen by the person as illegal; and (2) by employing persuasive tactics that will induce the person to commit the illegal act when that person originally had no intention of committing it.From the information given above, it can be validly concluded that, if an undercover officer named Ron arrests a suspect named Sheryl for an act they have discussed beforehand,
