With the exchange rate recently passing 1,500 won to the dollar, the decisions of people who had been weighing a U.S. green card are visibly wavering. The question that comes up most often in consultations is the same one: is it right to start now, or right to wait until the exchange rate settles down?

On the surface the answer looks simple. The rate is high, so the cost burden has grown, and waiting seems reasonable. But once you work through actual cases, this turns out to be less a question of "the exchange rate" and more a question of "timing."

■ The Exchange Rate Affects Cost; a Green Card Is Affected by Time

A green card process is not a project that wraps up in a short period. An EB-3 case typically takes three to five years, and longer depending on circumstances. EB-2 also requires considerable time once the PERM process and visa bulletin movement are taken into account.

Over that long stretch, the exchange rate keeps changing. It has in fact risen and fallen repeatedly over the past several years, and the rate at any one moment almost never determines the success or failure of an entire green card project.

The variables that matter more in a green card case lie elsewhere: the priority date, the visa bulletin, a child's age, and current immigration status. These factors do not become more favorable as time passes. In most cases the structure is the opposite — the later it gets, the greater the risk.

In the end, a green card isn't "a game you start when the exchange rate is low." It's "a game you enter at the right time."

■ Waiting Is Not Always the Safe Choice

Many people hope that "if I just wait a little, the rate will come down." But this judgment leaves out one assumption: that nothing happens while you wait.

Reality is different.

The visa bulletin can retrogress again at any time. There have in fact been several sharp retrogressions in the past, and each time a wide gap opened between those who were ready and those who were not.

For families with children, aging out is a very real risk. A difference of a few months can decide whether a child can be included in the green card process at all.

Current immigration status is another variable. For someone in the U.S. on a nonimmigrant status such as H-1B or F-1, a schedule that gets tangled can complicate the green card process itself.

In other words, choosing to wait isn't simply "a strategy for saving money" — it's "a decision to take on time risk."

■ The Bigger Cost Isn't the Exchange Rate — It's the Cost of Delay

When the exchange rate rises, upfront costs feel considerably heavier. Some expenses can look as though they have gone up by more than 10 to 20 percent.

Over the long run, though, a different variable looms larger: the opportunity cost created by delay.

Suppose obtaining a green card is pushed back by one year. The difference that year makes is not merely a matter of numbers. Employment opportunities in the U.S., income level, a child's educational environment, and the stability of one's stay are all affected.

For anyone intending to build a career in the U.S., in particular, when the green card arrives is not just a status question — it becomes a factor that determines the pace of career growth.

The result can be a structure in which you end up paying more in "time" than the amount you were trying to save on the exchange rate.

■ In an Era of a High Exchange Rate, the Approach Has to Change

That said, ignoring the exchange rate and pushing ahead regardless is not the right answer either. In a situation like the present one, a more strategic approach is called for.

The first element is a stage-by-stage strategy. A green card does not incur all of its costs at once. Because expenses are divided across stages such as PERM, I-140, and NVC or I-485, it is important to begin with the early stages and secure a priority date. From there, you can spread risk by adjusting the following stages while watching how the exchange rate moves.

The second element is an individual risk analysis. A child's age, current immigration status, job requirements, and the employer's situation all differ from person to person. In the very same exchange-rate environment, one person must start now while another can adjust the schedule.

The third element is judging by "structure" rather than by "the exchange rate." The exchange rate is an external variable, but the structure of a green card process is something you can design. What matters is understanding the structural advantages you gain by starting now.

■ Who Should Start Now, and Who Can Wait

The same answer does not apply to everyone.

If a child's age is close to the threshold, if current immigration status is unstable, or if the visa bulletin is open, moving quickly is advantageous regardless of the exchange rate.

Conversely, if there is ample time, procedural risk is low, and short-term exchange-rate movement can be put to use, a strategy of adjusting the pace at certain stages is also possible.

What matters is judging accurately what "now" actually means for you.

■ The Exchange Rate Is a Variable, but Timing Is Strategy

The exchange rate is certainly an important variable. But it should not become the standard that decides whether to move forward with a green card.

A green card is ultimately a question of timing. The outcome changes depending on when you start, and that difference creates an impact that goes well beyond cost.

The exchange rate can change if you wait.
The timing of a green card, however, will not wait for you.
