他先後在 Xerox, StorageTech and Sun Microsystems工作後，逐漸意識到運用他的人際交往能力能使他獲得更大的滿足感。所以他開始從事輔導亚裔美國高管的工作，最終開了餐館，取名Volcano Asian Cuisine，促進中西文化交流。
根據新美國經濟(由紐約市市長 Michael Bloomberg 創立的移民改革聯盟)最近的一份報告顯示，十分之一的科羅拉多州居民，或者說大約533,000的人口像鄭傑一样，出生在其他國家。
他目前的雇主CoCal Landsape有可能得不到該計畫的分配名額。 CoCal全年固定員工約127人，但需要額外僱用160人才能應付春季和夏季的工作激增。
該公司的創始人J. Chuey Medrano說，儘管在奧巴馬政府的推動下，此類臨时填補工作的工資已經從每小時少於11美元提升到接近每小時14美元，但是填補工作在當地依然很難招到員工。
今年的情況看起來更加糟糕。去年底，The Adams County公司在第一輪申請中申請了33,000份簽證，但一個都沒有申請下來。該公司在1月份再次申請，但有可能只能申請到季節性工作的工人，其中有些人自2000年以來每年在科羅拉多州工作六個月。申請狀況看起來並不樂觀。
“這些工作人員對科羅拉多州各轄區來說至關重要，特別是在我們的旅遊和戶外休閒行業。 一個確實有效的方案來改善簽證計畫將有利於科羅拉多州的經濟發展”星期二，Sen. Michael Bennet寫信給國土安全局部長 John Kelly，信的內容是關於H-2B簽證上限問題。
Medrano 說：“工人繳納稅款，支付租金以及購買食物。 他們的工作很辛苦，本地工人甚至都不會申請這樣的工作。 當景觀美化季節高峰期結束後，他們不要求失業救濟金，而是回國。
約占移民創業公司五分之一的最大的行業是專業和商務服務 - 幫助其他企業經營的企業。
去年，特朗普總統最親密的顧問中的兩位，Steven Bannon 和 Stephen Miller表示擔憂，自1970年以來，美國的移民人口已翻了四番。在科羅拉多州，移民人口自2000年以來上升了45.1％。
按照目前的移民率， Pew 研究中心估計，在2015年，勞動適齡人口是1.73億，到2035年將上升到1.83億。但如果没有移民，劳动人口将下降到1.66億。
科羅拉多州大約73.3％的移民年齡在25至64歲，占本地人口的52.1％。 移民占25歲以下人口的15.4％，65歲以上人口的11.4％。 包括移民子女在內的當地人占35歲以下的總人口的35％，和占65歲以上的人口有12.9％。
說到科技方面，移民做了巨大的貢獻，開創了Google，eBay和 Tesla等突破性的公司。 “財富”500強中約有40％的公司是由移民或其子女創立的。
新美國經濟研究總監Angela Marek Zeitlin說，在科羅拉多州，移民開的公司包括CH2MHill，Ball Corp.和 Level 3 Communications。
“這不完美， 美國並不完美。 但依舊是我的國家。”她寫道。

As a Mexican native and U.S. citizen, Luis Estrada initially viewed President Trump’s stance on immigration as political posturing, an effort to score points with his base of supporters.
But he glimpsed a darker attitude toward immigrants when a friend without legal status asked him to serve as guardian of his young son if the time came he were suddenly deported to Mexico.
“They don’t know what is going to happen to them,” Estrada said of people living in the U.S. without proper documentation. Reports of recent Immigration and Customs Enforcement raids followed by quick deportations have left immigrants without legal status on edge. How do they plan to stock their businesses and create their budgets when living with such uncertainties?
Estrada, a clean-cut and soft-spoken accountant by training, worked his way up from a laborer to a supervisor at a Denver-area landscaping firm. He said he has stopped watching TV news to avoid getting even more discouraged about dialogue that increasingly paints immigrants and immigration as bad for the country.
The political discourse centers mostly on illegal immigration, primarily from Mexico, which peaked in 2007, according to the Pew Research Center. Some local immigrants worry an increasing number of Americans are turning a jaundiced eye on anyone who wasn’t born in the United States, regardless of their legal status to live in the country.
Nationally, immigrants provide workers the U.S. will desperately need as baby boomers retire from the workforce. Many immigrant workers take jobs that natives either don’t want or aren’t available to fill. Immigrants and their children also represent an important source of innovation and entrepreneurship, and are behind several of the country’s signature companies.
“This country evolved into the leader we are today because of immigration, because of the global melting pot,” said Jie Zheng, a native of China who has lived in the country for 25 years.
Zheng tried for three years to get a student visa so he could leave China to study in the U.S. He initially intended to return, but his advanced skills in polymer chemistry put him in high demand during the color printing revolution of the early 1990s.
Those skills made Zheng a high priority for a work visa and green card. Eventually, that led to U.S. citizenship.
After a career spent at Xerox, StorageTech and Sun Microsystems, Zheng realized using his people skills was more satisfying. He began mentoring Asian-American executives and eventually started his own restaurant, Volcano Asian Cuisine, where he could promote cross-cultural exchange.
Looking back, Zheng said many of his friends who stayed behind in China did very well, given the growth that country experienced. When the opportunity came up to pursue a more lucrative career path with Xerox that took him back to China, he chose to keep his feet firmly planted in this country.

One in 10 Colorado residents, or just under 533,000 people, were, like Zheng, born in another country, according to a recent report from the New American Economy, an immigrant reform coalition founded by former New York City Mayor Michael Bloomberg.
Those immigrants represented $10.8 billion in spending power, paid $3.3 billion in taxes, and own more than 32,000 businesses employing more than 83,000 people in Colorado in 2015.
“We have a thriving community and state because of their contributions,” said Thamanna Vasan, an economic policy analyst with the Colorado Fiscal Institute. “There is a lot of misconception about the role that immigrants play in our economy.”
The New American Economy, a coalition of political and business leaders from across the U.S., supports more secure borders and a reduction in illegal immigration, which totals about 163,000 people in Colorado. It also supports creating a path for undocumented immigrants who obey the law, pay taxes and learn English to achieve legal status.
The group supports reforms that allow the best and brightest foreign students to remain in the country, while also advocating for the streamlining of visa programs to allow foreign workers to take hard-to-fill jobs.
Estrada initially came to the U.S. under the H-2B visa program, which is popular with seasonal employers, like ski resorts and landscaping firms, and permits up to 66,000 workers from outside the country to fill jobs across the U.S. after local hiring efforts fail.
His current employer, CoCal Landsape, is at risk of not getting an allocation under the program. CoCal employs about 127 workers year-round, but needs another 160 to handle the surge in work that comes each spring and summer.
Despite creative recruiting efforts and a boost in hourly pay from less than $11 to nearly $14 an hour, something the Obama administration promoted, filling the jobs has been a tough sell locally, said J. Chuey Medrano, the company’s founder.
“We compete with construction and oil and they pay a whole lot more,” he said. Last year, the company lost $1 million in revenues due to worker shortages.
Things are looking more dire this year. The Adams County company applied late last year under the first round of 33,000 visas, but didn’t get any. The company applied again in January, but the chances it can bring back its seasonal workers, some of whom have worked six months a year in Colorado since 2000, don’t look promising.
“These workers are vital to communities across Colorado, especially in our tourism and outdoor recreation industries. Determining efficient ways to improve the visa program will benefit Colorado’s economy,” Sen. Michael Bennet wrote to Secretary of Homeland Security John Kelly on Tuesday regarding the cap on H-2B visas.
Part of the problem is that there aren’t enough visas given the demand. That scarcity causes some companies to request more visas than they need, and re-allocating the unused visas can get complicated.
“The workers pay taxes, they pay rent, they buy food,” Medrano said. They take physically intense jobs that local workers won’t even apply for. And when the peak landscaping season ends, they don’t claim unemployment benefits, but return home.
Medrano came to the United States without a visa in the early 1970s, a time when crossing the California border didn’t involve as much effort or risk. He pursued legal status and then citizenship. He worked hard, became a manager and studied what it took to run a successful business.
Eventually, he moved to Colorado and started his own landscaping firm. As a business owner, Medrano said some of President Trump’s campaign points, such as lower taxes and less regulation, resonate with him.
But when it comes to immigration, the administration is going down the wrong path, he argues.
“Everybody sees it from their side of the table, but we are hard-working people, and a lot of us are entrepreneurs” Medrano said.
Many immigrants, legal or not, work in agriculture, construction, manufacturing, professional services, hospitality and food service.
About 11 percent of foreign-born immigrants in Colorado are self-employed, according to the New American Economy. Of the Colorado firms immigrants have started, 17.2 percent are in construction, 10.1 percent in retail, and 10.5 percent in hospitality or food service.
The biggest sector, accounting for about one out of five immigrant-founded firms, is professional and businesses services — businesses that help other businesses operate.
“The misconception is that immigrants are low-skilled and low-wage workers only. They are as likely to be professionals. They keep our economy going,” said the Fiscal Institute’s Vasan.
Last year, Steven Bannon and Stephen Miller, two of President Trump’s closest advisers, expressed concern the country’s immigrant population has quadrupled since 1970. In Colorado, the immigrant population has risen by 45.1 percent since 2000.
The anti-immigration camp argues that the country has gone through immigration “on” periods followed by long immigration “off” periods, and that the time has come to “turn off” immigration.
But what would an immigration off period mean for faster economic growth, a signature goal of the new administration?
At current rates of immigration, the Pew Research Center estimates the number of working-age adults, at 173 million in 2015, will rise to 183 million by 2035. But remove immigration, and the number of working-age adults drops to 166 million by 2035, Pew estimates.
Blame the big demographic bulge of baby boomers who are retiring in ever larger numbers. Without immigration, the country moves down the path of demographic stagnation that has plagued Japan’s economy, where adult diapers outsell baby diapers.
About 73.3 percent of Colorado’s foreign-born residents are age 25 to 64, versus 52.1 percent of the native-born population. Immigrants represent 15.4 percent of the population younger than 25 and 11.4 percent of the population age 65 plus. Natives, which include the children of immigrants, are 35 percent of the total residents younger than 25 and 12.9 percent of those older than 65.
When tearing apart the math that allows for GDP gains, a growing labor force is vital, and that doesn’t happen easily with a stagnant or declining population. Another driver is increasing productivity, or the use of training and technology to generate more output from each worker.
When it comes to technology, immigrants have made a huge contribution, launching Google, eBay and Tesla, among other groundbreaking firms. About 40 percent of companies in the Fortune 500 were founded by immigrants or their children.
In Colorado, that group includes CH2MHill, Ball Corp. and Level 3 Communications, said Angela Marek Zeitlin, research director with the New American Economy.
Zheng agrees with those who say that illegal immigration needs to be addressed, but worries that the contributions legal immigrants play is getting lost in the conversation. Competition is global now, and that isn’t going to change. The U.S. needs to engage the world, not pull away from it, he said.
“You need to have immigration to bring in fresh ideas,” he said. “Or the world is going to go around you.”
Zheng recalls an essay his daughter wrote in middle school in which she mentioned a small flag, damaged in the corner, that he had saved from his citizenship ceremony in 2008.
“It is not perfect. America is not perfect. It is still my country,” she wrote.
