Credit building roadmap

A 12-month plan to build a strong US credit score from scratch, for H-1B visa holders, new immigrants and anyone starting over in the US.

5 stages5 common mistakes

Target scores

The FICO bands, and the stage of the plan where a new file usually reaches each.

FICO score	Band	Typical stage
300–579	Poor	Starting point
580–669	Fair	6 months of on-time payments
670–739	Good	12 months of credit history
740–850	Excellent	2+ years of clean history

Two different starting points

Rebuilding a damaged file and building one from scratch need different work in a different order. Make sure you are on the right one.

Rebuilding a damaged file

You have a score already, but late payments, collections, high balances or a bankruptcy are holding it down.

Credit Roadmap

Building a file from nothing

You are here

You are new to the US, or new to credit, and have little or no history for a lender to read at all.

What makes up your FICO score

Factor	Weight
Payment historyThe biggest single factor. Pay every bill on time, every month. What one 30-day late costs depends heavily on what your file already looks like — roughly 90–110 points on a clean, high-scoring file, but only about 15–35 on one that already carries delinquencies.	35%
Credit utilizationBalances as a share of your limits. Under 30% is the floor, under 10% is where it stops holding you back. Unlike the rest of this list it is not historical — it unwinds as soon as a lower balance is reported, which makes it the fastest lever you control.	30%
Length of credit historyThe age of your oldest account, your newest, and the average of all of them. Do not close old cards — you keep the limit and the age by leaving them open, and closing one can raise your utilization overnight.	15%
New creditEach hard inquiry costs roughly 2–10 points and fades within about a year; opening the account itself costs another 5–20 or so by pulling down your average age. Rate shopping for a mortgage or auto loan inside a 14–45 day window counts as one inquiry.	10%
Credit mixHaving both revolving credit (cards) and installment loans (auto, personal, student) helps a little. It is the smallest factor on this list — never take on debt you do not need just to improve your mix.	10%

12-month action plan

Follow these steps in order for the fastest credit build.

When	What to do
Month 1–2	Open a secured credit card Apply for a secured card from Discover, Capital One, or your bank — these accept applicants with no credit history Deposit $300–$500 as collateral (this becomes your credit limit) Use the card for one small recurring charge (e.g., Netflix, gas) Set up autopay for the full statement balance
Month 2–4	Consider a credit-builder loan Self Inc. and credit unions offer credit-builder loans specifically for this purpose You make monthly payments; the funds are held in a savings account and released to you at the end Reports to all three bureaus — adds installment loan diversity and payment history Typical term: 12–24 months, $25–$50/month
Month 4–6	Monitor and optimize Check your credit score monthly at no cost: Credit Karma (TransUnion/Equifax), Experian app, or your bank Verify all accounts are reporting correctly — errors are common and must be disputed Keep utilization below 10% at all times (pay down before the statement date, not just the due date) Do not close the secured card, even if you get a better card — account age matters
Month 6–12	Upgrade and expand At 6–12 months with on-time payments, you may qualify for unsecured cards with rewards Ask your secured card issuer to "graduate" you to an unsecured card — many do this automatically Apply for one rewards card (cash back or travel) if your score is 680+ Avoid store cards — they have low limits and high interest rates
Year 2+	Build toward mortgage and auto readiness Score of 750+ typically qualifies for the best mortgage rates Add a second travel rewards card if you are organized and pay in full monthly Consider an authorized user arrangement if your employer or spouse has an old account Keep old accounts open — the length of history compounds over time

Common mistakes to avoid

1
ITIN
An Individual Taxpayer Identification Number (ITIN) allows you to file taxes but is not connected to a credit file. You need to open credit accounts that report to Experian, Equifax, and TransUnion.
Does not build credit
2
Indian credit scores
CIBIL and other Indian bureau scores are not recognized by US lenders. You start from zero in the US regardless of your credit history in India.
Do not transfer
3
Debit cards
Using a debit card or paying cash builds zero credit history. You must use credit products that report to bureaus.
Do not build credit
4
Closing old accounts
When you close a credit card, you lose that account's age contribution and available credit limit. Keep old accounts open even if you rarely use them.
Hurts your score
5
Carrying a balance
You do not need to carry a balance to build credit. Pay in full every month to avoid interest while still building history. The myth that carrying a balance helps is false.
Does not help
