How long until the whole family can go? — the first question nearly every family asks, and also the most hastily answered. The few months advertised only covers one piece of the journey: the USCIS review. The real journey starts much earlier — from the day your Vietnam company audits itself — and ends later: when your family settles in the US.
This article lays out the entire journey on a single timeline, divided into six consecutive stages: preparing your Vietnam foundation, establishing your US branch, drafting your petition, USCIS review, consular interview, and logistics before departure. Each stage includes realistic timeframes and variables that compress or extend it — so your family can plan with numbers instead of promises.
The Big Picture: Two Scenarios, Fast and Standard
Fast scenario — your Vietnam company is already in order: approximately 6 to 9 months from decision day to departure. Standard scenario — your company needs foundation cleanup: 12 to 18 months. The difference sits almost entirely in the first stage; the later stages remain fairly consistent across cases.
What's worth noting: the longest stage is also the only one completely within your family's control. How fast or slow USCIS processes is not your decision — but whether your company gets clean early or late is. That's why starting early is the biggest timeline lever.
Stage 1 — Preparing Your Vietnam Foundation: 3 to 12 Months
This stage has a detailed separate article; on the timeline, it includes: comprehensive review and weakness diagnosis (2-4 weeks), cleaning up finances and standardizing salary and insurance for the petitioner (3-9 months if you need to accumulate 12 months of payroll records), strengthening personnel structure and documenting authority in writing (running parallel), and gathering and translating documents (4-6 weeks, parallel to the next stage).
The biggest variable: bookkeeping. A company with audited financials, reconciled taxes, and the owner on formal payroll compresses this stage to 3-4 months. A company with dual books or an owner who's never been on payroll needs a full 9-12 months for paper trails to form naturally. There's no healthy shortcut here.
Stage 2 — Establishing Your US Branch: 2 to 3 Months, Can Run in Parallel
Forming the entity (1-2 weeks), obtaining EIN (fast if you have an SSN, 4-8 weeks through manual processing if not — start as early as possible), opening a business bank account (1-3 weeks depending on the bank and foreign ownership), transferring initial capital through official channels (2-4 weeks including procedures on both ends), leasing office space and setup (2-6 weeks), and writing business plan and staffing plan in parallel (3-5 weeks, multiple review rounds).
Critical timeline tip: Stage 2 overlaps with the second half of Stage 1 — once your Vietnam foundation is clear, start the US side immediately rather than waiting to finish sequentially. With an acquisition route, replace the above steps with target search - due diligence - closing: add 3-6 months but significantly compress later stages and even the EB-1C timeline.
Stage 3 — Drafting and Filing I-129: 4 to 8 Weeks
Once both sides have materials ready, your attorney builds the petition: support letters through multiple rounds of feedback (2-3 weeks), assembling four evidence groups and exhibit index (1-2 weeks), cross-review of everything — company checks the numbers, attorney checks the legal side (1 week), and filing with a decision on premium processing.
This stage's speed depends almost entirely on how fast your company provides documents and responds to drafts. Designate one single point of contact to work with the attorney, responding within 48 hours — this simple rule typically saves a full month compared to everyone having opinions and no one deciding.
Stage 4 — USCIS Review: 15 Business Days or Many Months
With premium processing ($2,805): USCIS responds within 15 business days — approval, denial, or RFE. Without premium: standard queue varies many months depending on timing and processing center. For a new office case where your family is scheduling life around the result, premium is essentially the default choice.
If you receive an RFE: add a response preparation cycle (2-8 weeks depending on what they ask) and USCIS review time after receiving your response. A wise timeline always reserves buffer for this scenario rather than treating RFE as a disaster — with new office cases, it's a realistic possibility that belongs in your plan.
Stage 5 — Consular Interview: 3 to 8 Weeks
After I-797 approval: complete DS-160 for everyone, pay fees, schedule interview — wait time varies by season and case volume at the consulate. After the interview, the typical outcome is your passport with visa returned within a few business days.
The administrative processing scenario adds weeks to months — uncommon but real, and the reason for one iron rule: don't book plane tickets, don't finalize house and job decisions on your projected schedule until the visa is in your passport.
Stage 6 — Logistics Before Departure: 4 to 8 Weeks
Visa in hand, the final stretch is family logistics: arranging remote management for your Vietnam company (should have started in Stage 1, now finalize), requesting school leave and withdrawing records for children, gathering settlement documents (birth certificates, marriage certificates, school transcripts, vaccination records — officially translated), arranging housing and property, and scheduling first-week tasks in the US per the settlement guide.
This stretch is purely within your control and can run parallel to Stage 5 at the preparation level — only finalize irreversible decisions (quitting jobs, selling assets) after visa arrives. Well-prepared families typically depart within a month of receiving their visa.
Three Biggest Variables That Shift Your Timeline
- Your Vietnam company's cleanliness: variable number one, up to 9 months difference between scenarios — and the only variable your family controls completely.
- RFE: adds 1-3 months; reduce probability with a strong petition from the start, reduce damage with buffer in your plan.
- Interview scheduling and administrative processing: external variables, protected by the rule of not finalizing irreversible decisions before visa arrives.
Advice in summary: plan for the standard scenario, work toward the fast scenario, and absolutely do not schedule your life around the best-case scenario. Families that maintain this discipline move through this process with far lighter hearts.

Frequently Asked Questions
What's the fastest my family can realistically depart?
Fast scenario in reality: 6-9 months from decision day — provided your Vietnam company is already in order (clean books, owner on formal payroll, established personnel structure) and you use premium processing. If your company needs foundation cleanup, the standard scenario is 12-18 months, with the difference sitting almost entirely in the Vietnam preparation stage.
Does premium processing speed up the entire timeline?
It compresses exactly one segment: the USCIS review stage to 15 business days instead of many months — very worth the cost since that's the most uncertain waiting period. Other stages (company preparation, petition drafting, interview scheduling) don't change, so your total timeline still measures in many months.
Should I quit my job and sell my house before I have a visa?
No — the iron rule of any timeline: only finalize irreversible decisions after your visa is in your passport. Your interview could fall into extended administrative processing, and every stage has delay probability. Prepare everything to ready status, but keep your exit route open until the final moment.
How does acquiring a US business differ from starting new on the timeline?
Add 3-6 months for target search - due diligence - closing, but in return: your first visa may be valid for 3 years instead of 1 year (removing early renewal pressure), and the 1-year operation requirement for EB-1C is essentially already met — your total timeline to green card is usually shorter even though the front end is longer.
