美国绿卡排期计算器与绿卡晴雨表

A visa bulletin tracker is an online tool that translates the monthly Visa Bulletin tables published by the U.S. Department of State into readable timelines. It helps green card applicants monitor queue progress and estimate when their priority dates will become current.

A green card priority date tracker is a utility that allows visa applicants to log their priority dates and compare them against the latest official cutoff dates to see how many months or years they are behind the line.

For employment-based green cards, the priority date is the date the PERM labor certification was filed with the DOL, or the date the I-140 petition was filed if PERM is not required. For family-sponsored categories, it is the date the Form I-130 petition was officially filed with USCIS.

Final Action Dates (Chart A) control when a green card can actually be approved or when an immigrant visa can be issued. Dates for Filing (Chart B) indicate when applicants can submit their application packages to the NVC or file their I-485 Adjustment of Status forms, depending on USCIS monthly rules.

Visa retrogression occurs when the official visa cutoff dates move backward chronologically rather than advancing. This happens when the demand for green cards in a specific category or country exceeds the remaining statutory limits for the fiscal year.

A retrogression alert is a warning that notifies applicants when cutoff dates move backward. It signifies that applicants whose dates were previously current may no longer file their I-485 applications until the dates advance again.

The visa wait time calculator measures the mathematical distance in days between your priority date and the active cutoff date. It then projects your estimated wait time using historical movement rates (like the 12-month rolling average or a pessimistic multi-timeframe pace).

The Visa Bulletin is updated monthly by the U.S. Department of State. Each edition outlines the cutoff dates for the upcoming calendar month.

The Department of State usually releases the Visa Bulletin between the 10th and 18th day of each month for the upcoming month's visa queues.

Cross-chargeability allows an applicant to use the country of birth of their spouse (or parent, in some cases) to charge their green card. This is highly beneficial if the spouse was born in a country with a shorter waiting line than the applicant's country of birth.

The Child Status Protection Act (CSPA) provides a formula to protect dependent children from 'aging out' (turning 21) during long visa queue delays. It allows the time a petition was pending with USCIS to be subtracted from the child's physical age when the visa becomes available.

U.S. law imposes a strict 7% per-country limit on green cards for any single nation. Because India and China have massive volumes of high-skilled applicants, their queues become heavily backlogged, while countries with lower applicant volumes remain current.

Consular processing is for applicants residing outside the U.S. who apply for an immigrant visa at a U.S. embassy or consulate. Adjustment of Status (Form I-485) is for applicants already inside the U.S. on a temporary visa (like H-1B or F-1) who petition to change their status to permanent resident.

A letter 'C' (Current) means there is no backlog for that specific category and country. Visas are immediately available, and eligible applicants can file their green card petitions regardless of their priority date.

A letter 'U' (Unavailable) means that the annual statutory limit of visas for that category has been completely exhausted. No immigrant visas or green card approvals can be issued until the new fiscal year starts on October 1st.

You can track your place by comparing your priority date against the monthly Visa Bulletin cutoff date. Tools like Visa Bulletin Check allow you to view historical movements and receive average wait estimations.

When your date is current, you can submit your Adjustment of Status (I-485) if you are inside the U.S., or complete consular processing at a U.S. Embassy. USCIS or the NVC can then adjudicate your case and issue your green card.

Yes. If visa numbers are exhausted or demand suddenly spikes, the State Department will move the cutoff date backward (retrogression) to pause new filings.

A priority date checker is a web utility that validates whether your priority date is current or not based on your specific category (e.g. EB-2, EB-3) and chargeability country.

The per-country cap limits any single nation to receiving no more than 7% of the total family-sponsored and employment-based green cards issued in a given fiscal year.

Employment-based categories are pathways for foreign workers: EB-1 (Priority Workers), EB-2 (Advanced Degree/Master's), EB-3 (Skilled/Professional), EB-4 (Special Immigrants), and EB-5 (Investors).

Family-sponsored categories are pathways for relatives of U.S. citizens and LPRs: F1 (Unmarried adult children of citizens), F2A (Spouses and minor children of LPRs), F2B (Unmarried adult children of LPRs), F3 (Married children of citizens), and F4 (Siblings of citizens).

An approved Form I-140 establishes your employment-based immigration category and secures your priority date. The priority date is locked and can generally be ported to a new employer if needed later.

Form I-130 approval confirms that a qualifying family relationship exists between a U.S. sponsor and a foreign relative, securing the relative's place in the family-sponsored immigrant visa backlog.

You lock your priority date in employment-based categories by obtaining an approved Form I-140. In family-based categories, your priority date is locked on the date USCIS receives your Form I-130 filing.

Yes. Under certain conditions (such as moving from EB-3 to EB-2 with the same or a new employer), you can carry over or 'port' your previously established priority date to the new petition.

USCIS processing times represent how long it takes officers to review and process a form (like I-485) once it is filed. The Visa Bulletin determines *when* you are legally allowed to submit that form based on global visa quotas.

The National Visa Center (NVC) manages consular processing. They contact you (creating your fee bill case) when your priority date is close to becoming current under the Chart B (Dates for Filing) guidelines.

No. Filing Form I-485 allows you to stay and work in the U.S. legally while your case is pending, but approval is subject to meeting all eligibility requirements and having a current priority date at the time of final adjudication.

If you have a pending I-485, you can travel only if you have an approved Advance Parole (AP) document or hold a valid dual-intent visa (such as H-1B or L-1). Traveling without AP or a dual-intent visa will abandon your I-485 application.
